Which is why in many cases you'll see that males are more often afflicted with these sex-linked disorders. Indeed, improvements in the tools used to study this class of disorders have enabled the assignment of specific contributing gene loci to a number of common traits and disorders.

Because human males need to inherit only one recessive mutant X allele to be affected, X-linked disorders are disproportionately observed in males. As a result, males are affected more often by X-linked recessive conditions, including color blindness, Duchenne muscular dystrophy, and hemophilia.

Both groups of disorders exhibit a distinctive pattern of non-Mendelian inheritance termed anticipation, in which, following the initial appearance of the disorder in a given family, subsequent generations tend to show both increasing frequency and increasing severity of the disorder.

An example of a sex-linked trait is red-green colorblindness, which is carried on the X-chromosome. Sex-Linked Traits If a gene is found only on the X chromosome and not the Y chromosome, it is said to be a sex-linked trait. Because the gene controlling the trait is located on the sex chromosome, sex linkage is linked to the gender of the individual. Usually such genes are found on the X chromosome.
