Sex-linked

Referring to genes which are linked to X chromosomes.


Referring to characteristics such as colour-blindness which are transmitted through the X chromosomes.


Describing genes (or the characteristics controlled by them) that are carried on the sex chromosomes, usually the X chromosome. The genes for certain disorders, e.g. hemophilia, are carried on the X chromosome. Since these sex-linked genes are recessive, men are more likely to have the diseases since they have only one X chromosome; women can carry the genes but their harmful effects are usually masked by the dominant (normal) alleles on their second X chromosome.


The term pertains to genes or traits that are located on one of the sex chromosomes, typically the X chromosome.


A form of inheritance specific to genes located exclusively on the X chromosome. In conditions like red-green color blindness and hemophilia, recessive genes play a role in determining the traits. Consequently, these conditions are more common in males because the Y chromosome lacks the corresponding genes or alleles, which, if present, would mitigate the impact of the recessive genes found on the X chromosomes.
