Among the sheep, wool color shows incomplete dominance. Sheep with white wool (WW) and a sheep with black wool (BB) are homozygous expressions of their corresponding allele. The heterozygous condition results to gray wool color (WB). A gray sheep mated to a black sheep. What are the genotypes of the parents?

• WB x WB

• WB x BB

• WB x WW

• WW x BB
