They don't. There are two types of twins, fraternal and identical. Current research shows no genetic connection to having Identical twins, anyone can have them.
Fraternal twins are caused by a female trait, dropping more than one egg at a time. There appears to be evidence that the trait can be inherited. While it appears to be on the mother's side of the family, it is certainly possible that this could be transmitted on the male side as well. This double dropping also occurs with older women as well.
yes! however two man can only father fraternal twins (twins from two separate eggs and sperms)
Yes, biologically it is possibgle but it requires a bizarre set of circumstances:
you need two egg cells to mature at approximately the same time (preferably from separate ovaries).
Identical twins will have the same father, so a paternity test is done just like for any kid. With fraternal twins, it is possible, but very, very rare, to have different fathers for the babies.
They can share some DNA, since your mother/father was involved in them.
Its a combination of your mom's and you dad's. Identical twins have the same dna
they were triplets
Identical Twins are the result of a single fertilized egg spliting in two producing two genetically identical children. Fraternal twins are the result of the mother producing two eggs each fertilized by a different sperm from the father. This can result in opposite sex twins.
fraternal twins can have separate fathers.

Sure, same as for a single birth.
Same father (half sibling)
triplets
If you are 2 of 3 triplets or 2 of 4 quads, etc, then you would not be twins but you would have been born to the same parents at approximately the same moment.
They can share some DNA, since your mother/father was involved in them.
nobody noes except GOD or they could be triplets or more
They will think "why my father is always so tied?"
Its a combination of your mom's and you dad's. Identical twins have the same dna
Ted and Ed are two of a set of triplets born together, with a third sibling. This means they share the same birthday, time of birth, and parents, but are not twins.
The father's name for the Casey twins in Jagged Edge is Thomas Krasny.
