Sex-Determination

A sex-determination system is a biological system that determines the development of sexual characteristics in an organism on the basis of the presence of the XY chromosome combination in the cells of genetic males in the cells of genetic females.

In placental mammals, the presence of a Y chromosome determines sex. Normally, cells from females contain two X chromosomes, and cells from males contain an X and a Y chromosome. Occasionally, individuals are born with sex chromosome aneuploidies, and the sex of these individuals is always determined by the absence or presence of a Y chromosome. Thus, individuals with 47,XXY and 47,XYY karyotypes are males, while individuals with 45,X and 47,XXX karyotypes are females.
