Encyclopedic overview
Some chromosomal sex determination systems in animals 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. This can be due to parthenogenesis, the act of a female reproducing without fertilization, mostly seen in plant species. In some plants or algae the gametophyte stage may reproduce itself, thus producing more individuals of the same sex as the parent.
