Inheritance of Feather Color in Chickens

Understanding Codominance in Chickens

In some chickens, the gene for feather color is controlled by codominance. The allele for black is B and the allele for white is W. The heterozygous phenotype is known as erminette (BW).

Questions:

a. What is the genotype for black chickens?

a. The genotype for black chickens is BB.

b. What is the genotype for white chickens?

b. The genotype for white chickens is WW.

c. What is the genotype for erminette (black and white) chickens?

c. The genotype for erminette (black and white) chickens is BW.
