X-linked genes have distinctive inheritance patterns because they are present in different numbers in females (XX) and males (XY). Every individual must have at least one X chromosome. In humans, the term often refers to traits or disorders influenced by genes on the X chromosome, as it contains many more genes than the smaller Y chromosome.
