Sex-Linked Genes are Found on Either the X Chromosome or the Y

Question

Sex-linked genes are found on either the X chromosome or the Y chromosome but not both.

Accepted Answer

Sex-linked genes are found on either the X or Y chromosome, but not both. This is because males have one X and one Y chromosome, while females have two X chromosomes. Therefore, a gene on the Y chromosome can only be inherited by males, while a gene on the X chromosome can be inherited by both males and females, but the inheritance patterns differ between the sexes.
