Question

A scientist has a pea plant with yellow seeds. It has one allele for yellow seeds (Y) and one for green seeds (y). Which describes the genotype of the pea plant?

Answer 1

heterozygous

Step-by-step explanation:

We see that because yellow seeds are denoted with a capital letter (Y), yellow seeds are dominant over green seeds (denoted by lowercase y). That means if a plant is yellow, the possible genotypes would be YY or Yy.

Here, the scientist has a yellow-seeded pea plant, so the genotype is either YY or Yy. The problem says that the plant has one Y allele and one y allele, which means its genotype is Yy. Another name for this is heterozygous.

Answer 2

D. heterozygous
