ANATOMY

Detailed explanation-1: -In the given case, the generation of black and white speckled offspring is an example of inheritance known as codominance, not multiple alleles.

Detailed explanation-2: -Gray: 100% Cross a BLACK chicken (BB) with a WHITE chicken (WW). These alleles show INCOMPLETE DOMINANCE.

Detailed explanation-3: -This phenomenon is termed incomplete dominance . The color of feather of chicken in question is similar to flower color of Mirabilis jalapa . The black color is represented by allele B and white color by allele W, as neither of these allele can dominate over the other.

Detailed explanation-4: -In chickens, the black (B) and white (W) alleles for feather color are codominant. If a homozygous white chicken is crossed with a homozygous black chicken, the offspring has feathers that are both black and white, a trait that is known as erminette, as shown in the diagram.

Detailed explanation-5: -The allele for black feathers is B and white feathers is W. The heterogenous genotype is known as erminette. Erminette chickens will look “spotted”.
