If white wool (w) is dominant over black wool (w), can two sheep with black wool produce an offspring with white wool? explain your answer.

This is the exact

No, the offspring of two black sheep cannot have white wool. Since the black wool allele is recessive, both parents have to be homozygous recessive (ww) and so do not carry the dominant white wool allele. The only allele the parents can pass to their offspring is the black allele.

Yes, two sheep with black wool may produce white wool offspring.

Explanation:

If two black wool sheep are heterozygous dominant (Ww) then a recessive allele carried by them would be donated or when combined with each other.

Therefore, a white wool sheep would be produced as it receives the phenotype of white wool along with the genotype ww.
