A particular species of potatoes can have red or yellow skin color. The skin color is
controlled by a single gene with two alleles, the red allele and the yellow allele. When
potatoes are homozygous for red skin color are crossed with potatoes that are homozygous
for yellow skin color, 100% of the offspring have red skin color. Based on this information,
how do the alleles for skin color interact?
