Codominance/Incomplete Dominance

Codominance: both traits in heterozygotes are expressed equally and separately.

In some varieties of chickens, the allele for black feathers (B) is codominant with the allele for white (W). Heterozygous chickens will have an erminette phenotype that appears as speckled with black and white feathers (BW).
