In chickens, the allele for black feathers is co-dominant with the allele for white feathers. Black-feathered and white-feathered birds are for either the black (B) allele or the white (W) allele. The genotype of an offspring of a black rooster and a white hen is and has a of (BW). The of the offspring shows.

In chickens, the allele for black feathers is co-dominant with the allele for white feathers. Black-feathered and white-feathered birds are homozygotes for either the black (B) allele or the white (W) allele. The genotype of an offspring of a black rooster and a white hen is heterozygous and has a genotype of (BW). The phenotype of the offspring shows some with white and some with black.

Explanation:

Co-dominant alleles cannot mask one another’s expression. This results when an allele from each of the homozygous parent are combined. The offspring produced will have phenotypes from both the parents and hence becomes heterozygous.

Hence the offpsring’s genotype produced by combining a co-dominant black rooster and a white hen becomes heterozygous and will demonstrate features (phenotype) with both black and white feathers.

ok

explanation:

blue stars have the highest surface temp

stellar distances are usually expressed in light-years

the measure of a star's brightness is called magnitude

hope this !
