The Punnett square below shows the cross between two parents heterozygous for two traits. In horses, the allele for black color (B) is dominant over the allele for white color (b). Long hair (H) is

dominant over the short hair (h).
1. What are the genotype and phenotype of the offspring in block A, B, C, D, and E?
2. What is the probability of getting a black horse with short hair?

See the attached table of genotypes.

A black horse with short hair has genotype Bxhh, where the x can be either B or b. According to the table, 3 of the 16 possible genotypes match this pattern, so the probability is 3/16.
