In a group of fruit flies, some individuals have a gray body and others have a black body. In this group, the gene for the body color trait has two alleles. The allele B is for a gray body, and the allele b is for a black body.

Question

In a group of fruit flies, some individuals have a gray body and others have a black body. In this group, the gene for the body color trait has two alleles. The allele B is for a gray body, and the allele b is for a black body.

A certain fruit fly is from this group. This fruit fly's phenotype for the body color trait is a gray body. This fly's genotype for the body color gene is Bb

Answer 1

. This fruit fly inherited one allele for a gray body (B) from one parent and one allele for a black body (b) from the other parent, resulting in a genotype of Bb. This genotype allows the expression of the gray body phenotype.
