Study Notes
Sex Determination in Humans
- The SRY gene on the Y chromosome triggers male development in humans in the XY sex-determination system.
Sex Determination in the XY System
- The XX chromosomes determine the homogametic sex (female) in the XY sex-determination system.
Klinefelter Syndrome
- Klinefelter syndrome involves individuals with XXY chromosomes, a genetic condition where males have an extra X chromosome.
Genetic Makeup of a Seemingly Normal Female
- A seemingly normal female with XY chromosomes but the SRY gene has been shut down is a rare occurrence, where the individual lacks the trigger for male development.
Survival in XY Sex Determination
- To survive in most species with XY sex determination, an organism must have a functional SRY gene or a compatible genetic makeup to trigger male development.
