Mendel crossed true breeding 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 (8,023 total). Which of the following statements correctly describes the relationship of the allele for green seeds to the allele for yellow seeds?
A) The green allele is dominant to the yellow allele.
B) The two alleles exhibit incomplete dominance.
C) The green allele is recessive to the yellow allele.
D) The two alleles are codominant.

The green allele is recessive to the yellow allele because the yellow seeds were more prevalent in the F2 generation, following a typical Mendelian 3:1 ratio for a dominant (yellow) to recessive (green) trait inheritance.
