Fraternal twins: Fraternal twins are more common in some families and in some ethnic groups. The highest twinning rate in the world is in africa. Fraternal twins are caused by two separate eggs developing at once, being ovulated at the same time, and being fertilized. Older women having a pregnancy have a higher rate of fraternal twins.
