if you have fraternal twins in your maternal line at all, there is a higher chance of you having fraternal twins, or hyper-ovulation. if your father was a fraternal twin, he could pass the gene of hyper-ovulation onto his daughter. But there isn't an answer to identical twins from what I read, that it was just at random.
Are twins hereditary?
My boyfriend's father is a twin and my aunt conceived triplets naturally.. I wasn't sure if twins were only hereditary on the mothers side if at all? My first Dr appt is in 2 weeks so I'll find out but was just curious :)
