The color of plumage in chickens is determined by the B gene localized on the X chromosome. The dominant allele of gene B determines the development of striped plumage, and the recessive allele b – black. Determine what offspring to expect from the cross:
1) striped chicken and black rooster;
2) striped chicken and heterozygous striped rooster;
3) a black chicken and a homozygous striped rooster.

1) Striped cockerels and black hens in a 1: 1 ratio;
2) striped cockerels, striped hens and black hens in a ratio of 2: 1: 1;
3) striped cockerels and striped hens in a 1: 1 ratio.
