what gene is sry located on
The SRY gene is located on the short arm of the Y chromosome. This gene is necessary in male sex determination. It initiates the series of events that will assist in the development of the male testes. Mutations in SRY give rise to XY females with gonadal dysgenesis who appear to be normal females at birth, but at puberty do not develop secondary sexual characteristics, do not menstruate, and have fibrous gonads without eggs.
