A scientist has a tomato plant with red-skinned tomatoes. It has one allele for red skin (R) and one for yellow skin (r).

Question

Which describes the phenotype of the tomato plant?

red skin
yellow skin
homozygous
heterozygous

Answer 1

The phenotype of the tomato plant refers to its observable characteristics. In this case, the plant has one allele for red skin (R) and one for yellow skin (r), making it heterozygous (Rr). However, the dominant allele (R) determines the phenotype.

Therefore, the correct description of the phenotype of the tomato plant is red skin.
