Question

My Institution Upload Assignment: Genetics Problem Set In the following hypothetical pedigree, there are two traits considered. One gene determines if a person is a vampire or not; the other gene determines if a person is a werewolf or not. The two genes sort independently. Study the diagram from the syllabus then answer the questions below. (HINT: Examine each trait separately when working out the genotypes.) (a) Is being a vampire due to a dominant or recessive allele? How can you tell? (b) Is being a werewolf due to a dominant or recessive allele? How can you tell? (c) Give the most likely genotypes for individuals I-2, Il- 3, and ll-6. Use D and d for the alleles of the vampire gene and R and r for the alleles of the werewolf gene.

Explanation / Answer

A) Is being a vampire due to a dominant or recessive allele? How can you tell?

When examining this pedigree, we have to consider the two genes separately. At first, we will see if an individual is a vampire or not. Vampire is dominant. Just look at the mating of II-3 and II-4. Both are vampires, but they have a normal (non-vampire) son.

B) Is being a werewolf due to a dominant or recessive allele? How can you tell?

In this case, we have to consider the werewolf trait, ignore the vampire trait. Werewolf is recessive. Consider the mating of II-6 and II-7. Both are normal (non-werewolves), but they have a werewolf child.

C) Give the most likely genotypes for individuals I-2, II-3, and II-6. Use D and d for the alleles of the vampire gene and R and r for the alleles of the werewolf gene.

Genotypes: I-2 is DdRr, II-3 is DdRr, II-6 is ddRr
