Image That You Self-Pollinate Heterozygous Purple-Flowered, Long-Pollened Pea Plants and Get

Image that you self-pollinate heterozygous purple-flowered, long-pollened pea plants and get mostly purple-flowered, short-pollened plants and white-flowered, long-pollened plants, with a very few purple-flowered, long-pollened or white-flowered, short-pollened plants. What is the most likely explanation?

A) One of the genes in question resides on a sex chromosome.
B) The genes are linked.
C) Long pollen is often lethal, so few plants with long pollen survive to adulthood.
D) This is a normal random variation from the expected ratio for independent assortment.
E) The purple allele influences pollen to become shorter.
