In chickens, the creeper phenotype is characterized by shortened legs and wings. Affected chickens cannot walk normally and have to creep along. Creeper chickens are heterozygous for he creeper allele, C. In the homozygous state, C disrupts embryological development and lead to death of the chicken before hatching a. What are the expected genotypic and phenotypic ratios from the cross of two creeper chickens? b. Is the creeper allele dominant or recessive for leg shape? Explain. C. Is the creeper...

2.(2) In Drosophila, black body colour is due to a recessive allele (b) and normal body colour is due to a dominant, wild-type allele (b+). If black bodied females are crossed to pure wild-type males, what phenotypic and genotypic ratios are expected if the F2 males are backcrossed to black-bodied parental females? Show your work.

In poultry, the allele B results in black feathers. Its recessive allele, b, produces yellow-splashed feathers. The heterozygous results in blue feathers. The dominant factors O and C are both required f any color at all in the feathers. Homozygous recessive at either locus results in white feathers. In each of the following 3 cases give the genotypes of the parental birds and their offspring, along with an...
