Sex-determination system

Biological system that determines the development of an organism's sex

A sex-determination system is a biological system that determines the development of the organism's sex. Most organisms that create their offspring using sexual reproduction have two common sexes, males and females, and in other species there are hermaphrodites, organisms that can function reproductively as either female or male, or both. There are also some species in which only one sex is present, temporarily or permanently.
