types of muscle cells

Males have one Y and one X chromosome whereas females have two X chromosomes. X-linked disorders are caused by a mutation on the X chromosome and both sexes can pass this to their children. If the mutation is a recessive gene and carried by the father, he has the disease since his only X-chromosome is mutant. His sons only receive his Y chromosome and thus are all normal. However, all his daughters receive his one and only defective X chromosome and become carriers.

In this example, an unaffected woman carries one copy of a gene mutation for an X-linked recessive disorder. She has an affected son, an unaffected daughter who carries one copy of the mutation, and two unaffected children who do not have the mutation.

X-linked recessive pattern of inheritance

Diseases inherited in an X-linked recessive pattern mostly affect males, because a second X chromosome usually protects females from showing symptoms.
