Two characteristics in tomato plants are stem color and leaf structure.

Stem color is determined by a gene with two alleles:

• Allele $G$ is dominant and results in a purple stem.
• Allele $g$ is recessive and results in a green stem.

Leaf structure is determined by a gene with two alleles:

• Allele $D$ is dominant and results in cut (lobed) leaves.
• Allele $d$ is recessive and results in potato-like (smooth margin) leaves.

The two genes are located on different chromosomes.

Two tomato plants are crossed:

• One parent plant has purple stems and cut leaves, and is heterozygous for both genes.
• One parent plant has green stems and cut leaves, and is heterozygous for the $D/d$ gene.
