WebSex-linked diseases are passed down through families through one of the X or Y chromosomes. X and Y are sex chromosomes. Dominant inheritance occurs when an abnormal gene from one parent causes disease, even though the matching gene from the other parent is normal. The abnormal gene dominates. But in recessive inheritance, … WebThe genes present on the X and Y-chromosomes are called sex-linked genes. Sex-linked genes on the X-chromosome are X-linked genes.

WebWhen a gene being examined is present on the X, but not the Y, chromosome, it is X-linked. Eye color in Drosophila, the common fruit fly, was the first X-linked trait to be identified. Thomas Hunt Morgan mapped this trait to the X chromosome in 1910. Like humans, Drosophila males have an XY chromosome pair, and females are XX. philly southWebDuchenne muscular dystrophy (DMD) is a serious disorder that causes progressive degeneration of the muscles.
