I believe that B and D are the only answers that I am sure of. C is incorrect and A seems incorrect as well. E may be a correct answer, but you will need to check the chemical equation. Hope this helps!
Well say the father had the genotype BB (dominant brown) and his mom had the genotype bb (recessive blonde).
If the boy got only one allele of brown hair and his phenotype is brown hair, then his genetic type is Bb
He is heterozygous (has two different alleles). But since brown hair is dominant, his phenotype is brown hair. But he does have the blonde recessive allele.
Hope this helps!
