SRY Gene

2.SRY Gene: Three cases of females with the SRY gene have been reported recently. These cases reinforce the SRY gene’s primary role in male development.

• About: SRY Gene found on the Y chromosome, it triggers male development. In its absence, development follows the female pathway.

oIt activates a cascade of genes that trigger the formation of testes in the embryo, which then produce testosterone, promoting male characteristics.

• Chromosomal Makeup: Humans have 23 pairs of chromosomes, including one pair of sex chromosomes: XX (female) or XY (male).

oFemale's Eggs  - carry X chromosome and Male’s Sperm either X or Y.

• SRY Gene Function: If the SRY gene is present and functional, the embryo develops into a male; if absent, it follows the female pathway.
