The gene for the black suit of cattle dominates over the gene for the red suit. What kind of offspring will be obtained from crossing a black bull with black cows, if it is known that all of them are heteroxyodic.

Let’s solve this problem using the scheme.

P: Aa (black heterozygous bull) x Aa (black heterozygous cow);

G: A, a x A, a;

F1: AA (black homozygous individual), Aa (black heterozygous individual), Aa (black heterozygous individual), aa (red homozygous individual).

Thus, 75% of the offspring will be black and 25% will be red.
