There is some genetic predisposition toward fraternal twins, but not everyone who has fraternal twins will carry the genes the predispose them to carrying fraternal twins. Some times it is just random chance taking over.
If the female in the marriage received from her mother (or from her father) the genetic predisposition for fraternal twins, she would be more likely to have fraternal twins herself.
If the male in the marriage received from his mother or father the genetic predisposition for fraternal twins he might pass it on to any daughters, and it would be more likely that he will have fraternal twins as grandchildren some day.
