males because they have a Y chromosome

Detailed explanation-1: -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. Males, who have only a single copy of the X chromosome, are more likely to be affected by a sex-linked disorder than females, who have two copies.
Detailed explanation-2: -X-linked, as related to genetics, refers to characteristics or traits that are influenced by genes on the X chromosome.
Detailed explanation-3: -X-linked recessive inheritance is a way a genetic trait or condition can be passed down from parent to child through mutations (changes) in a gene on the X chromosome. In males (who only have one X chromosome), a mutation in the copy of the gene on the single X chromosome causes the condition.
