Bateson and Punnett crossed two white-flowered lines and saw all purple flowers in the Fl generation. They concluded this was an example of complementary gene interactions because a cross of the F1 plants yielded_ A) 8 purple to 8 white B) 16 purple to 0 white D) 9 purple to 7 white 9) Most people with the dominant mutant polydactyly allele have extra digitsbut at least 25% hu of diaits What is the genetic explanation for this observation?
