Answered by GPT-5 mini AI
Such a gene is called a sex-linked gene (also called gonosomal).

More specifically:
- If it's on the X chromosome it's X-linked (e.g., red–green color blindness, hemophilia).
- If it's on the Y chromosome it's Y-linked (rare; affects males only).

Note: some genes lie in the pseudoautosomal regions of X and Y and are inherited more like autosomal genes.
