Geneticists examined the distribution of seed coat color in cultivated amaranth grains, Amaranthus caudatus. Crossing black-seeded and pale-seeded A. caudatus populations gave the following counts of black, brown, and pale seeds in the second generation. Seed Coat Color Seed Count black brown 342 71 pale 20 of all such seeds 3 According to genetics laws, dominant epistasis should lead to being black, brown, and pale.
