उत्तर
Morgan studied sex-linked genes in Drosophila by conducting many dihybrid crossings. He discovered that the F2 ratio differed from the 9 : 3 : 3 : 1 ratio, which is what is expected when the two genes are independent, indicating that the two genes did not segregate independently of one another.
