Post subject: I think it depends on what type of twins run in the family ?
For example if there are a lot of fraternal twins on your mums side it could be that the women in your family often release more than one egg every month,that can be something that is inherited but even if your mum or gran has twins it doesn't mean you will. Identicals come from just one egg so anyone can have them, I have heard there could possibly be a link on the male side as it could be something in the sperm that causes the egg to split For women though getting pregnant over 30 slightly increases the odds of non identicals as with age your body might struggle a bit more to get the egg out so might raise the hormone levels and that can result in two eggs, Clomid can have a similar effect as well . On average though its about a 1 in 80 chance for women not receiving hormone treatments
