Most male mammals , including male humans, have a Y chromosome , which codes for the production of larger amounts of testosterone to develop male reproductive organs .
Not all species share a common sex-determination system . In most animals, including humans, sex is determined genetically , but in some species it can be determined due to social, environmental or other factors. For example, Cymothoa exigua changes sex depending on the number of females present in the vicinity.
The existence of two sexes seems to have been selected independently across different evolutionary lineages (see convergent evolution ). The repeated pattern is sexual reproduction in isogamous species with two or more mating types with gametes of identical form and behavior (but different at the molecular level) to anisogamous species with gametes of male and female types to oogamous species in which the female gamete is very much larger than the male and has no ability to move.
