In terms of if the parents genes can cause multiple births, if the father has twins running in his family, or the mother has twins running in hers, we don't really know.
The conditions in the womb of the mother, the hormones she may have taken to help her conceive, and other factors are strong determinants whether the babies will be born.
However, if you check the family tree of the person you know with multiples and you may find out they may not be the only one in the family with multiples babies.

The tendency for multiple births comes from the maternal side.
Some women release multiple eggs, resulting in one or more being fertilized, to produce non-identical twins, triplets, etc.
Older, mutiple pregnancy, and certain ethnic groups have higher incidence of twins.
The incidence of identical twins is equal across the population.

I was told that the tendency to have non-identical twins came from the mother. That was because she would be the one releasing several eggs at a time from the ovaries that would subsequently be fertilized.
I was also told that the tendency to have identical twins was a trait passed on from the father's side of the family.
