WebDuchenne muscular dystrophy (DMD) is a serious disorder that causes progressive degeneration of the muscles. DMD is caused by recessive X-linked allele, meaning thag the defective allele that causes DMD is found only on the X chromosome. People affected with DMD usually do not have children, either by choice or because the condition prevents them. 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.
