6. In Drosophila melanogaster, the wild-type eye colour is dark red. A pure-breeding mutant strain with white eyes also exists. When reciprocal crosses are made between (i) a white-eyed male a wild-type female, and (ii) a white-eyed female a wild-type male, the progeny are as follows: (1) P: White-eyed male x red-eyed female F1: red-eyed males and females F2: 100 progeny; 27 red-eved males, 24 white-eyed males, 49 red-eyed females (ii) P: red eyed male x white-eyed female F1: white-eyed males and red-eyed females F2: 100 progeny; 23 red-eved males 26 white-eyed males, 28 red-eyed females, 23 white-eyed females. How do you interpret these data?
