Heterogametic sex

Sex linkage is the phenotypic expression of an allele that is related to the gender of the individual and is found on the sex chromosomes. This mode of inheritance is in contrast to the inheritance of traits on autosomal chromosomes, where both sexes have the same probability of expressing the trait. Since, in humans, there are many more genes on the X than there are on the Y, there are many more X-linked traits than there are Y-linked traits.
