Problem
You are investigating the trait of viral resistance in dogs (a mammal) that have heteromorphic chromosomes following the XY system. Your trait of interest maps to the X chromosome and follows a co-dominant inheritance pattern. In the population of dogs you are studying, there are 5 alleles (referred to as Vir1-Vir5), and the phenotypes are described by just the number (for example a Vir1/Vir3 genotype would have the phenotype "V1/V3").
What gametes are produced by the female, and in what proportions (please be sure to check both the gamete and the proportion are correct in the answer(s) you choose)?
