Question

Quizplus · Accepted Answer

Sex-linked genetic characteristics are encoded by genes located on the sex chromosomes (X and Y) and most are associated with X-linked conditions. Since males only have one X chromosome, any genetic variation on the X chromosome will be expressed in the phenotype. Females, on the other hand, have two X chromosomes which means that they can carry one copy of the gene variation without expressing it. Therefore, disabling sex-linked characteristics are more likely to appear in male phenotypes.
