In fruit flies, the allele for grey body, $G$, is dominant to the allele for black body, $g$. The outcome of a cross between two flies is shown below. Parent 1: grey-bodied fly \times Parent 2: black-bodied fly Offspring: 40 grey-bodied flies + 42 black-bodied flies What were the genotypes of the parents?
- Aparent 1: $Gg$, parent 2: $gg$
- Bparent 1: $gg$, parent 2: $Gg$
- Cparent 1: $GG$, parent 2: $gg$
- Dparent 1: $gg$, parent 2: $GG$
