Suppose that in sheep, a dominant allele (B) produce black hair and a recessive allele (b) produce white hair. If you saw a black sheep, you would be able to identify

• its phenotype for hair color
• its genotype for hair color
• the genotype of only one of its parents
• the phenotype of both of its parents
