A black cow is heterozygous (Bb) for coat color. She is bred to a black bull that is also heterozygous (Bb) for coat color. B = Black coat color, b = red coat color. She was successfully bred and is due to have a calf this spring. A. What are the possible gene combinations for coat color that their calf may be? (list the genotypes and the chances!) B. What are the possible colors (phenotype) and the chances (1/2, 1/4, 3/4, 4/4) their calf may be? C. What are the chances of their calf to be zygous dominant for a black coat?
