In corn, seedling color is determined by genes at two loci (C/c and D/d).  Suppose that you cross a pure-breeding green seedling with a pure-breeding yellow seedling and obtain only green seedlings in the F1 generation.  You then cross two of the F1 seedlings and obtain the following progeny for the F2 generation: 138 green seedlings, 33 virescent-white seedlings, and 10 yellow seedlings.  What form of epistasis would explain these data?

Inheritance and Mendelian Genetics

Inheritance means the passing of traits to offspring from parents. These traits could be passed either through asexual reproduction or sexual reproduction. The offspring receives the genetic material from the parents. Mendelian inheritance is a certain biological inheritance that follows the rules and principles laid down by Gregor Mendel in 1865. The initial hypothesis was considered wrong, but other inheritance theories modified the concept of inheritance and thus genetics.
