When calvin bridges observed a large number of offspring from a cross of white-eyed female drosophila to red-eyed males, he observed very rare white-eyed females and red-eyed males among the offspring. he was able to show that these exceptions resulted from nondisjunction, such that the white-eyed females had received two xs from the egg and a y from the sperm, while the red-eyed males had received no sex chromosome from the egg and an x from the sperm. what progeny would have arisen from these same kinds of non-disjunctional events if they had occurred in the male parent? what would their eye colors have been?
