In sheep, the allele for black wool (B) is dominant over the allele for white wool (b). Similarly, the allele for horns (H) is dominant over the allele for being hornless (h). Pure breeding horned sheep with black wool were crossed with pure breeding hornless sheep with white wool.
1. State the genotype and the phenotype of the F1 individuals produced as a result of this cross.
2. Two F1 offspring were mated together. Calculate the expected ratio of phenotypes in the F2 generation.
