Acctually, they're children would not look like twins. But all of their children would look like brothers and sisters.
Not necessarily you could be having twins and they don't have to be identical.
Well just because they are identical twins doesn't mean that they are the same person.
If you have two suspects who are identical twins, and you are trying to find out which one is the killer. Identical twins have identical DNA. However, identical twins do not have identical fingerprints, so you could just get a regular fingerprint sample instead.
No, even though twins do have identical DNA, they can have far different environments and life experiences. So, two identical twins though genetically the same could be very dissimilar in intelligence.
i say that identical twins are the least rare because like me a fraternal twin i only know 1 pair of fraternal twin.
Identical twins. Although horses sometimes have twins I'm not sure if they have identical twins.
Identical twins are the result of a single fertilized embryo splitting in two at an early stage and forming two viable embryos. As such, identical twins have identical DNA. Fraternal twins are the result of two distinct fertilized embryos being viable. As such, they have different DNA. They could even be different sexes.
If they were not then they would not be called identical twins!
Identical twins are formed from a single egg that splits into two. Fraternal twins are formed from two separate eggs that are both separately fertilized. So identical twins have identical DNA, and fraternal twins do not.
It is very unlikely that two brothers would have babies with the same DNA. That could only happen if identical twin brothers married identical twin sisters, and even then the mixing of DNA during reproduction makes this an extremely unlikely outcome.
Twins are identical because they come from the same egg.
