- Can ypu answer ALL parts to this question Pigment of chicken feathers is regulated by two genes, the gene for feather pigment C, and a gene that inhibits pigment production, I. A mother chicken, who is heterozygous for gene c, and heterozygous for gene I, is crossed with a father chicken, who is homozygous recessive for the pigment gene, and heterozygous for gene I. Inhibition is dominant to uninhibited, pigmented feathers are dominant to unpigmented feathers. The inhibitor gene (I) will prevent expression of pigmented chicken feathers. Use the letters C, c, I, and i for the genes. C is for color and I is for inhibitor Enter your answer as a list of haplotypes separated by spaces such as AB ab Ab aB. Do not write a sentence. Do not list duplicate haplotypes. Alphabatize your haplotypes, e.g. Ab, not bA. A) What are the potential genotypes of the gametes produced by the mother for these two genes?
