Detailed explanation-1: -The chances of having a chicken that is black and white from a mating between a black (BB) chicken with one black and white (BW) chicken will be 50 percent (50%). In genetics, codominance occurs when two alleles of the same gene are both expressed in heterozygous individuals.
Detailed explanation-2: -In chickens, coat color is a CODOMINANT trait, where black (B) and white (W) feathers are BOTH expressed. Individuals that have both alleles are speckled.
Detailed explanation-3: -Gray: 100% Cross a BLACK chicken (BB) with a WHITE chicken (WW). These alleles show INCOMPLETE DOMINANCE.
Detailed explanation-4: -In poultry genetics, both black (BB) and white (WW) are dominant. So breeding a black rooster with a white hen would result in a black-and-white chicken.
Detailed explanation-5: -In chickens, the allele for black feathers is co-dominant with the allele for white feathers.
