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.

Only individuals with a Y chromosome are affected in mammalian Y-linked inheritance and transmission can only occur from a sperm-producing parent. This is the easiest mode of inheritance to identify, but it is one of the rarest because there are so few genes located on the Y-chromosome. In 1960, the hairy-ear-rim phenotype ...
