In 1910, morgan did a series of experiments with the fruit fly drosophila, an organism where females are xx and males are xy. when a mutant male fly with white eyes was crossed with a wild-type female with red eyes, none of the f1 progeny had white eyes but 18% of the f2 flies had white eyes. unexpectedly, all of these white-eyed f2 flies were males. from these results, morgan concluded that the white eye trait is caused by a recessive allele located on the x chromosome. instead of fruit flies, suppose morgan had done his experiments with grasshoppers, where females are xx and males are xo. in this case, if a male with a recessive x-linked trait was crossed with a wild-type female, what would you expect among the f2 progeny?
