Sex Linkage

Genes associated with the X chromosome.

Sex-linked genes are also known as X-linked. See also sex-linked recessive.

Sex-linked genes are found in two copies in females but only one copy in males. As a consequence, females are twice as likely to display dominant traits associated with these genes than males while males are often much more likely to display recessive traits, though this increased likelihood is a function of allele frequency.
