Question:
My question is, has it been proved that the chances of having twins in families is hereditary?



Replies:
There is no positive hereditary link that has been identified for identical (monozygotic) twinning at this writing, however, there is a possiblity. Fraternal (dizygotic) twinning has more data to suggest it may well be inherited. 12/2005
