Y-linked disorders are caused by mutations on the Y sex chromosome. These conditions display may only be transmitted from the heterogametic sex (e.g. male humans) to offspring of the same sex. More simply, this means that Y-linked disorders in humans can only be passed from men to their sons; females can never be affected because they do not possess Y sex chromosome. Y-linked disorders are exceedingly rare but the most well-known examples typically cause infertility. Reproduction in such conditions is only possible through the circumvention of infertility by medical intervention[1].
Examples[2]
- Azoospermia
- Abnormal or Absent Testicular Development
- Retinitis Pigmentosa
