Fruit flies can be grey-bodied (GG) or black-bodied (gg). They may also have long wings (LL) or short wings (ll).
A. Use a Punnett Square to determine the genotypes and phenotypes of the following crosses: (you can use the table function in "Word" to make your Punnett Squares).
1. Monohybrid Crosses
a. Cross a homozygous grey-bodied fly with a heterozygous grey-bodied fly.
b. Cross a homozygous black-bodied fly with a heterozygous grey-bodied fly.
2. Dihybrid Crosses
a. Cross a heterozygous grey-bodied fly that is also a heterozygous long-winged fly with a heterozygous grey-bodied fly that is a short-winged fly.
b. Cross a black-bodied fly that is also short-winged with a fly that is heterozygous for both grey-body and long wings.
