    Suppose that in sheep, a dominant allele [B] produces black hair and a recessive allele [b] produces white hair. If you  saw a black sheep, you would be able to identify:

    A) Its phenotype for hair colour.

    B) Its genotype for hair colour.

    C) The genotypes for only one of its parents.

    D) The genotypes for both of its parents.

    Correct Answer: A

    Solution :

    [a] Blank is the phenotype of the sheep.  identify the genotype of a black sheep because it could be either BB or Bb. The possible genotypes of the parents of a black sheep could be BB x BB, BB x Bb, Bb x bb, or Bb x Bb. Thus, there is no single genotype for either parent.
