In a different land and a different time, you are a dragon breeder. Giant green dragons with horns that breathe red fire and have wings fetch the most money. The inheritance pattern for these traits is shown in Table 1. Homozygous Recessive bb-small +Table 1. Genotypes and phenotypes of different dragon traits Trait Homozygous Dominant Heterozygous Size BB - big Bb - big Color GG-green Gg-green Horns HH - horns Hh - horns Fire RR - yellow fire Rr - yellow fire Wings NN – wings Nn - wings gg - blue hh-no horns rr-red fire nn - no wings You have a male and female dragon with the valuable phenotype that you have recently bought to breed to produce more dragons with the valuable phenotype to sell.

(3 points) Provide a mathematical model(s) or diagram(s) for calculating the proportion of the sperm or eggs. Use variables (not numbers, unless they would not change) and provide a key. Make sure the model meets our criteria for mathematical models of biological phenomenon. 3B. (11 points) The mathematical model/diagram should apply to all calculations. To demonstrate that it works, explain how the model/diagram would be used to calculate the probability/proportion of INGBh sperm. Don't just plug numbers in. Explain where those numbers came from referring to the following biological processes: 1) Segregation of alleles during meiosis 2) Independent assortment of chromosomes during meiosis 3) Genetic recombination Remember to describe these processes in your explanation, not just repeat these phrases. Explain why you multiply or add. 3C. (11 points) Dragon buyers are fickle. The trendy dragon is now one that is small and blue has no horns, has wings and can breathe red fire as shown here: Write the possible genotype(s) of this dragon: Write a mathematical model for calculating the probability of producing any offspring genotype (include a key). Explain how this mathematical model represents the biological process of fertilization. Use the mathematical model to make a determination of whether the dragon breeder will be able to make a living by breeding the male and female to produce the small blue dragon with wings and no horns that breathes red fire. Make sure you show how you would calculate the probability of producing this dragon. Show your work/explain your reasoning so that we can see how you derived your answer and where your numbers came from. (A pair of dragons produce 4 offspring every year.) Work: Can the dragon breeder make a living by producing the two dragons he already has to get the new trendy dragon? Explain your answer.
