Razhie answered Tuesday November 22 2011, 9:24 pm: Depends. Did they have fraternal twins or identical twins?
If they had identical twins, then you chances are about the same as everyone else's. Identical twins are 'almost' random. Having a history of identical twins in your family only makes you very, very slightly more likely to have twins than a person who doesn't have a family history. (It should be said, some ethnicities do seem to have a greater occurrence of idenitcal twins...)
Fraternal twins do have a genetic component. Fraternal twins "run in families" on the mother's side only, if she inherits the gene for hyper ovulation. So your boyfriend's family history doesn't matter. Only yours. And if you carry the gene for hyper ovulation. (And it doesn't 'skip a generation' it just 'skips the guys' and only affects females.)
Of course, you CAN have twins without carrying the gene for hyper ovulation, but in that cases the chances of twins are the same roll of the dice as anyone else. [ Razhie's advice column | Ask Razhie A Question ]
