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: 6,022 yellow and 2,001 green. Which of the following statements correctly describes the relationship of the allele for green seeds to the allele for yellow seeds?
