A gene located on the X or Y chromosome is called which of the following?

Explanation:
Genes located on the sex chromosomes are called sex-linked. When a gene is on the X or Y chromosome, it’s described in common terms as X-linked because the X chromosome carries many such genes and often drives the patterns we observe, especially in males who have only one X. This distinguishes these genes from those on autosomes, which are on the non-sex chromosomes and follow typical Mendelian inheritance. It also distinguishes them from mitochondrial genes, which reside in mitochondria and are inherited maternally. Therefore, a gene on the X or Y chromosome is best described as X-linked.
