please helllpppp.

10. Budgies (Melanopsittacus undulatus) are attractive birds that come in many colors. Budgies may produce either or both of two types of pigment in their feathers: a blue pigment and a yellow pigment. Whether or not each pigment is produced is governed by one gene with two alleles. Blue pigment (B) is dominant to no blue pigment (b), and yellow pigment (Y) is dominant to no yellow pigment (y). A budgie that produces neither blue nor yellow pigment in its feathers looks white. A budgie that produces both blue and yellow pigment in its feathers looks green. A. What is/are the possible genotype(s) of a yellow budgie? B. What is the phenotype of a budgie with the genotype BbYy? C. Suppose you cross a homozygous blue budgie with a homozygous white budgie. Predict the results of this cross, both genotype and phenotype. D. Now suppose you cross one of the offspring from the mating in part C above with a budgie whose genotype is BbYy. Predict the results of your cross. What are the expected genotypes and phenotypes of the offspring from this cross, and in what ratios?
