Using a Punnett square workout the distribution of an autosomal phenotypic feature in the first filial generation after a cross between a homozygous female and a heterozygous male for a single locus.

Cross - $\displaystyle 1$ $\displaystyle GG \times Gg$(Homozygous dominant female × Heterozygous male)gametes: $\displaystyle G$, $\displaystyle G$ and $\displaystyle G$, $\displaystyle g$Cross - $\displaystyle 2$ $\displaystyle gg \times Gg$(Homozygous recessive female × Heterozygous male)gametes: $\displaystyle g$, $\displaystyle g$ and $\displaystyle G$, $\displaystyle g$
