The gene versions that increase the chance of hyperovulation can be passed down from parent to child. This is why fraternal twins run in families. However, only women ovulate. So, the mother’s genes control this and the fathers don’t.
What age are you most likely to have twins?
Those patterns were strongest in women aged 35 and older, followed by women aged 30-35, and lastly by women in their 20s. Fraternal twins develop when two eggs are fertilized.
