Which parent determines if there will be a multiple birth?

I know that identical twins result when one fertilized egg splits and that fraternal twins result when two separate eggs are fertilized (therefore 2 must be released). To me it is logical that the mother would at least determine if 2 eggs are released and if there is a possibility for fraternal twins but does anybody know about identical twins? My boyfriend is a twin (Fraternal) and twins are in my generation on my mom's side so I'm just trying to figure out our odds of having twins one day.Which parent determines if there will be a multiple birth?
Fraternal is the mother, i dont think identical is geneticWhich parent determines if there will be a multiple birth?
If twins run in either side, you have a chance of having twins. They generally go every other generation (so if your mom was a twin, you might have twins, but if your boyfriend's grandfather is a twin, you're probably safe).





Identical twins can also be caused by random mutation... ie, the egg just doesn't happen to split..





1 in 76 births is a twin. 1 in 76 twins is actually triplets. :)
Kimberlyn is right.
father.
Identical twins come from the father. Fraternal comes from the mother. Your chance are very good. Good luck!
