Compose answers to the questions below and save the file as a backup copy in the event that a technical problem is encountered while attempting to submit the assignment. Make sure to run a spell check. You will be submitting your answers to the lab assignment in two parts. The first part of the lab assignment consists of the laboratory exercise questions. The second part of the lab assignment is the application question. The first textbox on the submission page corresponds to the first part of the lab. Be sure to paste the laboratory exercise questions, with your answers, into this textbox. The second textbox on the submission page will be for your response to the application question. LABORATORY EXERCISE QUESTIONS ~~1. List whether you are positive or negative for each characteristic and include whether the characteristic is dominant or recessive. (6 points) a. Blood type b. Widow's peak c. Free ear lobes d. Tongue rolling e. Hitchhiker's thumb f. Left thumb dominance g. Little finger bend h. PTC taster i. Mid-digit hair j. Facial dimples k. Freckles l. Cleft chin ~~2. Can an individual tell if their blood type is heterozygous or homozygous? Explain. (5 points) ~~3. Create and label a Punnett square to determine the possibility of a couple having a color-blind child if the mother has the recessive trait on one X and the father is color -blind. HINT: Use Xb to indicate an X with the color-blindness trait. (4 points) 1 2 3 4 1. 2. 3. 4. ~~4. From your Question 3 Punnett square results, what percentage of female offspring will be color-blind? What percentage of male offspring will be color -blind? (2 points) ~~5. From the Human Karyotype Activity, what was the Karyotype Group number? What was the result of the karyotype? (Include the sex and the chromosomal disorder, if applicable. If there was no chromosomal disorder, you must state that the individual was normal.) (10 points) ~~6. Describe a situation, including an example, in which it wo uld be important to create a karyotype for an individual. (5 points) ~~7. Does a karyotype tell all of a person's genetic characteristics? Explain. (5 points) ~~8. Why is a photograph of cells in metaphase utilized when constructing a karyotype? (4 points) ~~9. Genetically speaking, why is it important not to mate with a close relative? Explain. (5 points) ~~10. What does it mean to be a carrier of a genetic defective characteristic? When might it be important to know if one is a carrier? (5 points) ~~11. Using your results from the hemophilia procedure, answer the following questions with a population of 120 individuals (n = 120): (4 points) A. What were the possible genotypes of the offspring? B. What is the probability (percentage) of males having hemophilia out of the entire population? C. How many females (what number of females) would have hemophilia out of the entire population? D. How many carriers (what number of carriers) would there be out of the entire population? ~~12. A student has a friend who is a Biologist, and the student is confused a bout her blood type. Her blood type is O, but her father has type A and her mother has type B. She asks her friend if it is possible for her parents to have a child with type O blood. What would be a clear and complete response the friend could give to answer her question? (4 points) ~~13. If a person were to have 14 children in a row, all female, what is the probability the next child would be a female? (2 points) ~~14. Explain why more males tend to suffer from X -linked disorders than females. (5 points) ~~15. An individual’s father is very tall. This same individual’s mother is very short. The individual’s height is somewhere in between. Is this codominance or incomplete dominance? Justify the answer. (4 points) ~~16. In the sickle cell activity, what happened to the percentage of surviving alleles that were HbA and the percentage of surviving alleles that were HbS over the course of the experiment? Why did this happen? (5 points) ~~17. Using the data from the sickle cell activity, will these percentages continue to change as they did in the first few generations? Why or why not? (5 points) APPLICATION QUESTION ~~18. (Application) How might the information gained from this lab pertaining to Human Genetics be useful to you, or how can you apply this knowledge to your everyday life as a non-scientist? The application will be graded according to the rubric below. (20 points)

Explanation & Answer

Hi! I have finished with this assignment :) There are only a few problems. For questions number 5, 11, 16, and 17, there were obviously other lab assignments. Since I have no way of knowing what they are about, or what their outcome was, I can not answer them. I simply left them blank for you to answer. If you have any questions or concerns, please let me know. I am attaching the answer as a .doc file.

lab assignment is the application question. The first textbox on the submission page
corresponds to the first part of the lab. Be sure to paste the laboratory exercise
questions, with your answers, into this textbox. The second textbox on the submission

LABORATORY EXERCISE QUESTIONS

~~1.
List whether you are positive or negative for each characteristic and
include whether the characteristic is dominant or recessive. (6 points)
a. Blood type - My blood type is B positive. This trait is dominant. I also possess the
D antigen.
b. Widow's peak - I do not have a widow’s peak. This trait is dominant.
c. Free earlobes - My earlobe is attached. This trait is dominant.
d. Tongue rolling - I can roll my tongue. This trait is dominant.
e. Hitchhiker's thumb - I do not have a hitchhiker’s thumb. This trait is recessive.
