SRY (Sex-determining Region Y)

The SRY, or Sex-determining Region Y, is a gene located on the Y chromosome that plays a crucial role in male development. It acts as a genetic switch, triggering the formation of testes, which produce male hormones like testosterone. This hormone development leads to the physical characteristics associated with males. Without the SRY gene, the embryo typically develops female features. Overall, the SRY gene is essential for determining male sex and initiating the biological processes that develop into male reproductive organs.
