In the sweet pea crossing experiment by Bateson and Punnet, the F2 generation had many more offspring with the phenotypes of purple flowers with long pollen (PL) and red flowers with round pollen (pl) than expected from independent assortment. This is because
A. in sweet peas, the alleles for flower color and pollen shape are on the same chromosome.

D. In sweet peas, the allele for flower color is in the nuclear genome and the allele for pollen shape is on the chloroplast genome.
