Medical Definition of Gene, Y-linked
Gene, Y-linked: A gene on the Y chromosome.
(Y-linkage is analogous to X-linkage (the presence of a gene on the X chromosome) in that it says a gene is on one of the sex chromosomes.)
It has often been said that little is known about genes that may be Y-linked. This is no longer true. As of the year 2012, about three dozen genes were known to be Y-linked including:

- AZF2 (azoospermia factor 2),
- BPY2 (basic protein on the Y chromosome),
- AZF1 (azoospermia factor 1),
- DAZ (deleted in azoospermia),
