In Andalusian fowls, black individual (BB) and white individuals (bb) are homozygous. A homozygous black bird is crossed with a homozygous white bird. The offspring are all bluish-gray. Show the cross as well as the genotypes and phenotypes of the parents and offspring

The genotype of a homozygous black bird is BB while that of a homozygous white bird is bb. The genotype of the offsprings is Bb

Explanation: A cross between a homozygous black bird (BB) and a homozygous white bird (bb) will produce four offsprings all with genotype Bb.

A homozygous black bird (BB) will manifest phenotypically as a black bird and a homozygous white bird (bb) will manifest phenotypically as a white bird while a heterozygous bird (Bb) will manifest phenotypically as bluish-gray bird.
