Are twins hereditary?

Question

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 :)

Answer

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.

Answer

It is through the mother that it can be hereditary.

Answer

It's passed from your father

Answer

if you google and read scholarly articles, ones written by professionals who do real research, they say identical twins are completely random no matter what. even if there are several sets of identical twins in a family, it's just coincidence. I'm not sure about fraternal because that has to do with the mother producing more than one egg during ovulation, and that may be hereditary, but I haven't read much on that.

Answer

Fraternal twins are more often conceived if you have fraternal twins that run in your family. This is because two eggs could drop instead of just one to become fertilized, this is hereditary.  However with identical twins, your fertilized egg will split, created two identical people, this will just happen naturally and has nothing to do with family traits :) hope this helps!

Answer

There is a genetic link for fraternal twins, and I think it can be passed by mom or dad (or both?). But identical twins are just a fluke.

Answer

I think it is from the fathers side
