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, they are twins. Being born on the same day to the same parents makes them twins, even if they are identical.
If identical twins have the same DNA, it would be impossible to determine which twin is the biological father based on genetic testing alone. In such a case, additional evidence or alternative testing methods would be needed to establish paternity.
They can share some DNA, since your mother/father was involved in them.
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.
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.
Same father (half sibling)
Yes, they are twins. Being born on the same day to the same parents makes them twins, even if they are identical.
triplets
If identical twins have the same DNA, it would be impossible to determine which twin is the biological father based on genetic testing alone. In such a case, additional evidence or alternative testing methods would be needed to establish paternity.
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.
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?"
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.
