Question description

Need someone helps me do the lab report.

All requests are in the uploaded file.

Please strictly follow the required format.

The format and requirements of the lab report are in Lab Report writing aid.pdf, please read carefully and strictly follow the required format.

The experimental method is in GeneticsLab.PDF, please note that In your written lab report, after the methods you need to do/provide the following:

1. A list of the genotypes in each of the parental (P1), F1 and F2 generations.

2. A description of the phenotypes expected in the F1 and F2 generations.

3. Your completed data table for your 30 F2 generation offspring, including a summary of the total number of each genotype and phenotype, and a calculation of the ratios of the observed F2 genotypes and phenotypes.

4. Contrast the phenotypes observed in the F1 and F2 generations. Provide an explanation for your individual F2 generation results based on the 30 offspring. Include in your answer, the phenotypic ratio that you might have expected in the F2 generation. If your answer differed from this theoretical ratio, explain what might have caused this.

5. Provide a summary of the group genotype and phenotype data in the second table. Calculate the genotype and phenotype ratios for these total group data. Is the phenotypic ratio now closer to your expected value? If so, what might explain this?


Experimental data in the pictures, two of the tables are the second part, and one table is the first part about black and yellow.

About corn part, we just got a hybrid corn and count the numbers of each type of kernel on it, there are two type: black and yellow.

Department of Biological and Environmental Sciences BIO L320 – GENETICS LAB Dr. Jacqueline Jones Laboratory II – Mendelian Genetics – Genetic basis of the Principle of Segregation in F2 progeny of a monohybrid cross. Monohybrid cross for maize: Inthis part of today’s lab, we will examine the F2progeny of amonohybrid cross for maize as described in Investigation 1, section VI B, pages 11-13 (New)9-11 (Old Book). You will be given ears of F2corn kernels to count. Use a marker to markstarting point for the count. Count the numbers of each type of kernel on each row, then move round to the other rows until you reach the marked starting point. Then total up the two different types of corn. Everybody in each group should count one corn kernel. Record your data in a copy of Table 1.3 (page 13-New Book) (page 11- Old Book). Note that the convention is to put the dominant phenotype in the upper row and the recessive phenotype in the lower row. If youdon’t want to tear page 13 or 11 from your lab book, make sure that you bring a photocopy of it to lab. For the drosophila portion, you can skip that until the flies are ready.  Write a short account of your corn counting experiment along with your corn data table (10 points).  Sampling exercise:Purebred wild-type smooth-seed pea plant males were crossed withpurebred wrinkled-seed females to produce F1 generation offspring. In peas, smooth-seed shape is dominant over wrinkled-seed shape (see text and Figs. 11.4-11.11 on pages 300-307 in thelecture textbook by Russell [2010] for example and nomenclature used for dominant and recessive alleles at this locus). You will be provided with two bags of cotton balls (eachcontaining 25 green (or red) balls [S – smooth allele] and 25 black (or white) balls [s – wrinkled allele]) that represent the gametes from F1 generation peas; one bag represents games from an F1 male and the other from an F1 female. You should draw out one gamete from each bag and pair them to obtain an F2 generation offspring individual. You need to record the genotype and the phenotype of this individual in the data table. You should repeat this process until you have 30 F2 generation offspring. You then need to calculate the observed ratios for the F2 generation genotypes and phenotypes. For the genotype ratios, calculate the total number of each genotype, then divide each by the smallest number to obtain the ratio – express as ratio of each of the larger numbers: 1 (i.e. 1.45:1 2.26:1). For the phenotype ratios, calculate the total number of each phenotype, then divide each by the smallest number to obtain the ratio – express as ratio of largest number: 1 (i.e. 2.76:1). When you have completed your particular draw, the ballsneed to be resorted so that there are 25 green (or red) balls and 25 black (or white) balls in each bag. Each individual in your group needs to conduct a draw of one ball from each bag tomake up 30 F2 generation offspring. Then compile a summary of the total group data, based on the genotypes and phenotypes observed.  In your written lab report, after the methods you need to do/provide the following:  1. A list of the genotypes in each of the parental (P1), F1 and F2 generations. 2. A description of the phenotypes expected in the F1 and F2 generations. 3. Your completed data table for your 30 F2 generation offspring, including a summary of the total number of each genotype and phenotype, and a calculation of the ratios of the observed F2 genotypes and phenotypes. 4. Contrast the phenotypes observed in the F1 and F2 generations. Provide an explanation for your individual F2 generation results based on the 30 offspring. Include in your answer, the phenotypic ratio that you might have expected in the F2 generation. If your answer differed from this theoretical ratio, explain what might have caused this. 5. Provide a summary of the group genotype and phenotype data in the second table. Calculate the genotype and phenotype ratios for these total group data. Is the phenotypic ratio now closer to your expected value? If so, what might explain this? Grand total for Lab 2 = 50 points. This lab report will be due in next lab. Reference: Russell, P.

TROY UNIVERSITY BIO L320 Genetics Lab HOW TO WRITE A SCIENTIFIC LAB REPORT GENERAL IN APA FORMAT: Scientific laboratory reports or any other APA style paper written at a collegiate level have a standard format. The following are standard for APA papers:  1 inch margins on all sides  12-point font and the font style should be either Arial, or Times Roman  Some type of Header (Running Head:)  Numbered pages except the Title Page  Paragraphs indented 1-tab space  DOUBLE-SPACED throughout the paper including Title Page and Reference Page. Scientific laboratory reports have a separate Title Page and a separate Reference page. scientific reports have HEADINGS on each section of the report. These headings are:  Introduction  Materials & Methods  Results  Discussion TITLE: The first page of the lab report is the TITLE page. Do NOT number the Title page unless instructed to do so. The title of the lab report should NOT be too general but should reflect more specifically about the experiment. For example: “Fingerprinting” is too general for the title but instead, use something like: “Fingerprinting as an Effective Forensic Tool in Solving Murders.” The title should be informative; it should not be “cute.” A Running head is needed as a Header on all pages including the title page. The Running Head should appear as Running Head: SHORT TITLE OF PAPER IN ALL CAPS (but not in bold). Compiled by Rashmee Silwal for use in BIO L320 TROY UNIVERSITY NOTE: The title is in Title case (first letter of each word is capitalized except nonessential words.)! The Title page information should be absolute centered on the page. The Title page should NOT be numbered! (unless instructed). The Title page must be doubled-spaced, have a center indentation and include the following information: Title Lab Number Your Name (author) Names of those in the experimental group (do not put “Group Members” next to names) Instructor Class name Name of Institution Date of submission Example: Laboratory II – Mendelian Genetics – Genetic basis of the Principle of Segregation in F2 progeny of a monohybrid cross LAB 1 Group Members: Jane College, Harry Potter, Norman Rockwell and Barry Allen Dr. Jacqueline Jones/ Ms. Rashmee Silwal Genetics Lab Biol320 (A/B) August 15, 2017 Compiled by Rashmee Silwal for use in BIO L320 TROY UNIVERSITY Introduction The paper must be written in THIRD person. Do NOT use I, me, we, them, they, he, she or us. The Introduction does just that: INTRODUCES the topic or concept on which an experiment was performed. It is in the Introduction where you explain the ideas or concepts and NOT the experiment. Explain why the topic is important and if needed, a short background. How does the topic relate to your experiment? You don’t have to make it too wordy if you can introduce your topic correctly. You will need to cite at least two references in your Introduction section. ALL resources (references) MUST be properly CITED in the Introduction. Correct in text citations for the APA format must be present. Helpful links are posted on your course syllabus in Required Textbooks and Supplementary Materials. It is considered PLAGIARISM if credit is not given. Always Paraphrase. Avoid using direct quotes. In the Introduction, NEVER:  Discuss results  Write in first person  Include information just to fill in space.  State how data were collected (data are plural!)  Use numerous quotes instead of paraphrasing. But, avoid paraphrasing that isn’t written in your own words!  Plagiarize literature reviews or anything else in the paper (use quotations if directly quoting otherwise paraphrase or use your own words)  Start the Introduction with “In this experiment…” or “We experimented on….”  Include unnecessary information. “A Sharpie was used…”  Be wordy!  Triple space between paragraphs or next Heading  Start the Hypothesis with “I hypothesize… or “My group hypothesizes…” or anything else that is first person.” Compiled by Rashmee Silwal for use in BIO L320 TROY UNIVERSITY The last paragraph in the Introduction is for stating the Purpose and Hypothesis. As it is a part of introduction, you don’t need a title for this. It’s just the end sentence or section on Introduction. The Purpose is stating why the experiment was performed. Do NOT make statements such as: “The purpose of this experiment is to learn more about solutions.” Or, “The experiment will help me learn more about fingerprinting.” Or better yet, “It’s part of my grade.” The purpose should be logical and scientific. Basically, what was the lesson learned? Materials and Methodology This section is used to describe HOW the experiment was performed. There should be enough information so that another researcher or layperson can repeat the experiment and get the same or similar results. This section is written in sentence (narrative) format DESCRIBING the materials and/or equipment used and EXPLAINING the steps taken to collect data. You should NEVER just LIST materials used and steps taken. These should always be explained in a narrative, sentence format. DO NOT LIST!!! Do not plagiarize information from the lab manual or experiment handout! This section should always be written in PAST TENSE since you have already completed the experiment. Remember that you are describing what you did or how you set up the equipment so that data was collected and what materials were used. However, you must include enough detail that another person could set up the experiment the same way you did! Do NOT make any statements about the data collected. This will be in the Results section. Do not include unnecessary information such as: “A blue sharpie pen was used to label….” Or “Three marks were made on test tube #1…” Use statements such as: “Three mls of water and 3mls of methylene blue were added to each of three test tubes marked 1-3.” Results This section is for PRESENTING the data that were collected in the experiment. Your presentation of the data should allow readers to draw some type of conclusion about your experiment. You MUST include Tables and Figures (graphs) in this section about the data you collected. All tables and figures should be described in NARRATIVE format. You MUST describe the data in a narrative form and not just insert a table or graph or some type of listing. Follow the sentence descriptive form as with any section of the lab report except you will also insert a table(s) and Compiled by Rashmee Silwal for use in BIO L320 TROY UNIVERSITY figure(s) displaying the mathematical data. You should NEVER DISCUSS what the data MEAN in this section. Other readers should be able to easily read and understand what was measured from the table and figure. TABLES AND FIGURES MUST BE NUMBERED and have an informative title. The number and title are placed ABOVE the Table or Figure and double-spaced. The information inside the table is not double-spaced. Figures are also numbered and can include Graphs, Charts and Illustrations Figures (Graphs, Charts and Illustrations) must have Legends, Specific Titles, X & Y axes named, numbered and a short explanation of the figure. Discussion In this section, you will EXPLAIN or analyze the results. The hypothesis(es) should be restated. Your conclusions should be well organized and thoughts not scattered about in different paragraphs. You can also in-text cite references again in the discussion to support your thoughts. In this section, your results are INTERPRETED! Why are the results the way they are? Are the data similar to previous experiments? INTERPRET! Were your group results similar to other groups? Why or why not? Include a short discussion as to whether the data SUPPORTED or did NOT SUPPORT your hypothesis. A hypothesis cannot be Right or Wrong! It cannot be correct or not correct or good or bad. A hypothesis can ONLY be supported or not supported by the data collected. Do not make statements in your discussion such as “The results showed that my hypothesis was right (or wrong).” There is no right or wrong! If your hypothesis is not supported by the data, it does not necessarily mean that you did something wrong. You may have not done the experiment correctly but more than likely, there were other factors that may have altered the outcome. Discuss whatever you may think was a factor and it went wrong. Assumptions about any possible ERRORS while collecting data should be discussed. Refer to the data to support your speculations about the experiment. Do not state that “something went wrong” or “I was not clear about the instructions.” Compare your group data to those of other groups to see if your data are similar to the other groups. Compiled by Rashmee Silwal for use in BIO L320 TROY UNIVERSITY The last paragraph should state the major findings of the experiment/study. References References are the scientific/scholarly articles from VALID and RELIABLE sources about similar studies. NEVER use WIKIPEDIA as a reference. It is NOT valid or reliable!! References for Scientific papers should be listed in APA (American Psychological Association Writing Journal) format. The best way to gather your references is to do a database search in the Troy Library resources or Goggle Scholar first. A book is another great source that can be cited. Other reliable web sites include WebMD.com, CDC.gov, nih.gov, or nih.gov/PubMed. The Reference Heading should be centered at the top of the page. The heading should NOT be in bold, italicized or underlined. References are never bulleted or numbered. References should be listed on a separate page and in alphabetical order. Basic Format for List of references at the End of the Lab Report : APA style dictates that authors are listed last name first followed by first name initials; publication year goes between parentheses, followed by a period. The title of the article is in sentence-case, meaning only the first word and proper nouns in the title are capitalized. The periodical or journal title is italicized and in title case (first letter of each word is capitalized except non-essential words such as in, of, a, and, etc…), and is followed by the volume number which, with the title, is also italicized. If there is an issue number, it is in parentheses next to the volume number and is not italicized. Page numbers are in the format xx-xxx. If the article was retrieved from the internet, include the URL. It should be written as Retrieved from then the web address. Author, A. A., Author, B. B., & Author, C. C. (Year). Title of article. Title of Periodical, volume number (issue number not italicized), pages. Retrieved from http://www.xxxx.xxxx For more help, its best to refer the Supplementary Materials listed on the Course Syllabus. Compiled by Rashmee Silwal for use in BIO L320

SEGREGATION
Abstract
The reason for the practical experiment was to examine the F2progeny of a monohybrid
cross for maize that would illustrate (Mendel's first law) law of isolation. Researcher Gregory
Mendel found the law of isolation and. The arrangement of the analysis was straightforward as it
included the checking of phenotypic characteristics of the maize-cobs. The F2 portion data was
recorded. From the data, we acquired critical information affirming our speculation for 3:1 for
the monohybrid crosses.
Introduction
The law of segregation was developed by researcher Gregory Mendel and is regularly
alluded to as Mendel's first law. According to Bateson and Mendel (2013), the segregation law
states that amid the generation of gametes, the two duplicates of each genetic factor will isolate
to such an extent that every posterity procure one component for each parent and that at a given
locus, alleles isolate int...
