Fl Generation: Red eyes males X White eyes female W+ W Red eye female White eye male w+ W Red eye female White eye male

Explanation / Answer

This hypothesis is given by Thomas Hunt Morgan.

A male fruit fly with white eyes rather than the normal red crossed the white-eyed male with a homozygous red eyed (W+W) female fly, then the all of the First generation(F1) offspring had red, which indicates that white eyes was a recessive trait as carry on to study fruit flies, and found that when crossed flies from the first generation, white eyes(WY) only appeared in males; thus he hypothesized that red eyes are dominant to white eyes and that the gene for eye color was located on the X chromosomes and not the Y chromosome. Heterozygous females had two X chromosomes. So, the dominant allele for red eyes covered the recessive allele for white eyes males, however only had one X chromosome .Thus, if males were white-eyed, they had inherited the X chromosome carrying the white eyed gene male have an XY genotype all of a male's sex-linked genes are expressed males have no second copies of sex-linked genes.
