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?

The plant’s genotype is Yy: it has one yellow-seed allele (Y) and one green-seed allele (y). Because the two alleles are different, the plant is heterozygous; yellow describes its seed color, not its genotype.
