Explanation:
Detailed explanation-1: -An allele W, for white wool, is dominant over allele w, for black wool. In a sample of 900 sheep, 891 are white and 9 are black.
Detailed explanation-2: -Dominant alleles are represented by capital letters and recessive alleles are represented by lowercase letters. For example, blue eyes are a recessive trait and brown eyes are a dominant trait.
Detailed explanation-3: -Black wool in sheep is recessive (w) to white wool which is dominant (W). A white ram is crossed with a white ewe. Both parents carry the allele for black (w). They produce a white ram lamb which is then back crossed to the female parent.
