Webinvolving sex-linked traits. 36 Objective 23 Other traits, besides sex, are controlled by genes on the sex chromosomes. These are called sex-linked traits. Traits controlled by the X are X-linked. Traits controlled by the Y are Y-linked. Since most sex-linked traits are controlled by the X, you can assume X-linkage, unless it says Y-linked.
