Based on this information, what is Holly's phenotype for the body hair trait?

 - a hairless body
 - a hairy body
You need to determine Holly's phenotype for the body hair trait. First, consider the alleles in Holly's genotype for the body hair gene. Then, decide whether these alleles are dominant or recessive.
The allele for a hairy body (B) is dominant over the allele for a hairless body (b). This means B is a dominant allele, and b is a recessive allele.
Holly's genotype of Bb has one dominant allele and one recessive allele. An organism with at least one dominant allele for a gene will have the dominant allele's version of the trait. So, Holly's phenotype for the body hair trait must be a hairy body.
