Twinning is really interesting stuff. When I was pregnant with mine (fraternal and almost 14 now) I got my hands on some of the twin research studies done by the U of Minnesota. Fraternal twinning has a genetic component. The likelihood to release more than one egg at a time is passed down from mother to daughter. Thus, my daughter has an increased chance of having twins but not my sons. My grandmother and my mother both had sets of fraternal twins.
Your chance of conceiving twins also varies depending upon your race, age, whether you've had multiples before, and even months of the year (according to the U of M twin studies, the month with the greatest chance of conceiving twins is February I believe). You are also more likely to conceive twins if you have a high amount of squash in your diet (I thought this one was funny).
