Suppose a group of researchers analyzed a new species of flowering plant. In this species, flower color is determined by two genes. They crossed a truebreeding red-flowered stock with a truebreeding white-flowered stock. They then crossed the F_1 offspring together and analyzed the next generation. Upon examining the flower color, they found that the F_2 generation contained 178 purple, 60 red, and 80 white flowers. What genetic term best describes the inheritance pattern of flower color for this species?
a. genes in one pathway
b. no gene interaction
c. dominant epistasis
d. recessive epistasis
