Mendel crossed yellow-seeded and green-seeded pea plants and then allowed the offspring to self-pollinate to produce an F₂ generation.The results were as follows: 6022 yellow and 2001 green (8023 total).The allele for green seeds has what relationship to the allele for yellow seeds?

Question

The allele for green seeds is recessive to the allele for yellow seeds, as it only appears in the F₂ generation when both alleles are present in a homozygous recessive genotype. This is supported by the ratio of 3:1 for yellow to green offspring in the F₂ generation, which is characteristic of a monohybrid cross with a dominant/recessive relationship between the alleles.
