|X-linked recessive trait||
A genetic trait that is apparent when all copies of the X-chromosome possess the gene; in men, this occurs when they inherit the trait from their mother, while women must inherit the trait from both parents. For this reason, X-linked recessive traits are almost always apparent only in men, while women are more commonly carriers of the trait.
A genetic trait found on the X chromosome; women have two copies of this chromosome, while men have only one.
