Stream-of-consciousness: Identical twins are always the same gender. However, identical twins are very rare. Most twin cases are formed from two different fertilizations during the same conception event. Non-identical twins can be opposite gender or same gender. <ibo> Ajụjụ: Ụmụ ejima nile hà bụ otu nwoke ma ọ bụ otu nwanyị? Mmetụta uche: Ụmụ ejima na-abụkarị otu nwoke na otu nwaanyị.
