The first one is fraternal twins (which are more associated with heredity) and the second one is identical twins.
However, because your husband's mother is a twin, it may put you at a slightly higher chance for a twin pregnancy. This chance would be higher if your mother or grandmother had a history of twin pregnancies.

twins are passed down through the mother's genes.
Sounds like a good chance! You sound like my family LOL!
Identical twins happen by chance only; 4 per 1000 births or 0.004 probability. Fraternal twin probability is increased only if it is on the mother's side; so this does you affect your circumstance (from what you have stated). The chance of fraternal twins is 1 in 60 or 0.017. So, your probability of identical twins is 0.004 and fraternal twins is 0.017 (BTW, I have triplets).
You have the same chance as the general population. Identical twins are a genetic accident, researchers still don't know what triggers an egg to split making two embryos from one fertilized egg.
Women who are themselves fraternal twins have a 10% chance of producing twins, identical twin women have only a 0.6% probability of having a twin birth.
