that was my point with the 'genetics' comment...

I think it's the mother that needs to have the predisposition for multiple births however, since a twin comes from either a split of the egg after fertilization or two being released by the ovaries and both being fertalized...

In any event, the probabilities of twins *given* a certain number of twins seen wasn't available... had it been, the numbers would have been very different indeed.
