Sex linkage is the patterns of inheritance and presentation when a gene mutation allele is present on a sex chromosome allosome rather than a non-sex chromosome autosome.

The way sex determination works in birds is nearly the reverse of how it works in mammals. Most single gene disorders are rare; but, in total, they affect millions of people in the United States. But in recessive inheritance, both matching genes must be abnormal to cause disease. X-linked recessive diseases most often occur in males.

Turn recording back on. Males have an X and a Y chromosome XY and therefore if one of the genes on the male's X chromosome has a change, he does not have another copy of that gene to compensate for the changed copy. In humans, generally men are affected and women are carriers for two reasons.
