Question

what are x-linked?

make it a simple 3 sentence

Answer 1

X-linked refers to genes located on the X chromosome, one of the two sex chromosomes in humans. Conditions caused by mutations in these genes generally affect males more severely since they have only one X chromosome, while females have two. This means that females can be carriers of X-linked disorders without necessarily showing symptoms, as they have a second X chromosome that may provide a functional copy of the gene.
