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.
What else can I help you with?
Two women apply for a job They are identical They have the same mother father and birthday The interviewer asks Are you twins to which they honestly reply?
Yes, they are twins. Being born on the same day to the same parents makes them twins, even if they are identical.
How do you determine who is the father if identical twins have same dna?
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.
Are twins genetic copies of each other?
They can share some DNA, since your mother/father was involved in them.
Was Esau and Jacob identical twins?
No, Esau and Jacob were not identical twins. They were fraternal twins, meaning they were born from the same pregnancy but did not have the same genetic makeup.
Why can fraternal twins be different genders but identical twins are are the same gender?
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.
Do identical twins always have the same father?
fraternal twins can have separate fathers.
How can a brother and sister be the same age but not twins or adopted?
Same father (half sibling)

Does the father contribute to indentical twins?
Yes, the father's genes contribute to the DNA of identical twins. Identical twins are formed when a single fertilized egg splits into two separate embryos, each carrying the genetic material from both the father and the mother.
I and my brother were born on the same moment to the same mother and father but we are not twins how is this so?
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.
Where do twins come from, the mother or the father?
Twins come from the mother, as it is the mother's body that releases the eggs that can be fertilized by the father's sperm to create twins.
Are twins genetic copies of each other?

Two babies born on the same day in the same year with the same mother and father are not twins?
nobody noes except GOD or they could be triplets or more
Does the father determine identical twins?
They will think "why my father is always so tied?"
Ted and ed are brother they have the same mother and father but are born on the same day same time same hospital but are not twins how is that possible?
He is the same person? No - this is a riddle. Ted and Ed have another sibling born at the same time, thus they are triplets, not twins.
