Codominance is a form of inheritance in which two different alleles for a gene are both expressed, and neither allele is dominant over the other. One example of codominance is feather color in erminette chickens; the alleles for black feathers and white feathers are codominant. If a homozygous white chicken and a homozygous black chicken mate, what would you expect to find in their offspring?

They will all have black feathers.

They will all have white feathers.

They will have feathers that will all be gray.

They will have a mixture of white feathers and black feathers.
