Sex-determining mechanisms in reptiles are broadly split into two primary groups: genotypic intercourse dedication (GSD) and temperature-dependent intercourse dedication (TSD).

Types within the group that is genotypic like animals and birds, have intercourse chromosomes, which in reptiles appear in two major kinds.
