A male bird is homozygous recessive for both wacky wings (w) and flashy feathers (f). He is crossed with a female who is homozygous dominant (normal wings and normal feathers) for both traits.What are the genotypes of these birds? (male; female)

Rooster feathering in chickens is inherited with the autosomal recessive allele r. Hen feathering is inherited with the autosomal dominant allele R. The trait is sex-limited, only males will show rooster feathering. A rooster-feathered male is mated to a hen-feathered female. All of the male offspring have rooster-feathering. What is the genotype of the hen-feathered mother?Multiple choice question.RRRrrr

Which of the following represents a heterozygous genotype?*rrAaYellow feathersRed and white spotted

Feather color in chickens can be black, white, or speckled (a mix of black and white). The genotypes of these color variations are shown above. Which pattern of inheritance is present in these chickens would be , and the phenotype ratio expected from a cross between a speckled hen and a black-feathered male would be ?

In some chickens, black feathers and white feathers are co-dominant traits. Chickens that have both a black feather allele and a white feather allele have black and white feathers in a sort of checkerboard pattern across their bodies.If two checkered chickens reproduce, what are the expected phenotype ratios in the offspring?Responses3 black : 1 white3 black : 1 whiteall checkered chicksall checkered chicks1 black : 3 white1 black : 3 white1 black :  2 checkered : 1 white

In a population of birds, the frequency of the recessive allele for feather coloration (a) is 0.25. Assuming the population is in Hardy-Weinberg equilibrium, calculate the following: The frequency of individuals heterozygous for the genotype (Aa).a.0.375b.0.5625c.0.0625d.0.9375
