My friend found out she is pregnant and she is wondering if she will have twins...her boyfriend is a twin, boyfriend's dad is a twin and boyfriend's granny is a twin...

As far as I know, the fact that twins are in her bf's family is completely irrelevant. Fraternal twins run down the mother's line because it requires her to ovulate twice (the bloke always sends loads of sperm) and identical twins are just a random occurrence, not hereditary.

Yes it carries down the female line, not male smile

Twins run down the fathers side, not mothers smile

I thought identical twins were a fluke of nature ?

That's really interesting, I do actually know of a family with 2 sets of ID twins. I always just thought they had both got lucky.
I have heard about the egg spiitting before fertilisation before.
My 2 are fraternal, it took ages to convince one friend that I was pregnant with twins, he didnt believe me because there were no twins in my family. grin

Yeah there's no twins in my family either and I've got fraternal twins.

Has to start somewhere.
