However, female carriers can contribute the trait to their sons, resulting in the son exhibiting the trait, or they can contribute the recessive allele to their daughters, resulting in the daughters being carriers of the trait.

Because human males need to inherit only one recessive mutant X allele to be affected, X-linked disorders are disproportionately observed in males.

A sex chromosome, (also referred to as an allosome, heterotypical chromosome, or heterochromosome, or idiochromosome) is a chromosome that differs from an ordinary autosome in form, size, and behavior.

Aug 11,  · Genes located on the X chromosome are called X-linked genes, and these genes determine X sex-linked traits.A mutation occurring in one of these genes could lead to the development of an altered trait.
