Question: in birds assume blue feather color is dominant to yellow...

Question details

In birds, assume blue feather color is dominant to yellow feather color and all animals are true breeding. A yellow-feathered male is crossed to a blue-feathered female. and the all of the male offspring have blue feathers while all of the female offspring have yellow feathers.

However, when the reciprocal cross is performed, blue-feathered male crossed to a yellow feathered female all of the offspring is blue. Please explain this result and indicate the genotypes of the parents and offspring from these crosses. (Hint: females are the heterogametic sex and have ZW sex chromosomes and males are the homogametic sex in birds with ZZ chromosomes).

a.Provide a genetic hypothesis to explain these results

b.Indicate the genotypes of the parents and offspring for the cross: yellow-feathered male x blue-feathered female resulting in all blue feathered males and all yellow-feathered females

c.Indicate the genotypes of the parents and offspring for the cross: blue-feathered male x yellow feathered female giving rise to all blue feathered offspring
