Because they separated into separate beings early in the cell division process. After that, a quadrillion factors are involved in the minuscule differences all along the development process. This is how they become different people.
Twins can have very similar DNA, especially in identical twins who come from a single fertilized egg that splits into two. On the other hand, fraternal twins are no more similar genetically than any other siblings. Some slight genetic differences can arise due to mutations that happen after the initial egg fertilization.
Yes they do because they are created from the same egg when it splits so they will have the same DNA because they are identical but on the other side regular twins don't have the same DNA because they are from diffrent egg and sperm
True. Each individual (except for identical twins) has a unique set of DNA that is inherited from their parents, resulting in genetic variations between different people.
Yes, identical twins have the same DNA because they are formed from a single fertilized egg that splits into two embryos. This means they share the same genetic information and are genetically identical.
yes they are... simmes twins form from one egg that is in the process of separating into two eggs or identical twins... but the process isn't finished and that is why they are "stuck together"
No, identical twins have the same DNA because they come from the same egg.
Identical twins come from a single fertilized egg that splits into two embryos, while fraternal twins come from two separate eggs fertilized by two different sperm. Identical twins share 100% of their DNA, making them genetically identical, while fraternal twins share about 50% of their DNA, like regular siblings.
Yes EVERYBODY has different DNA even if you are identical twins.
100%Identical twins develop from the same egg, so have the same DNA. The only thing different between identical twins is finger prints, and retinal patterns.
No
identical twins do. just not the same fingerprints.

Identical twins, due to the fact that the one fertilized egg splits, have identical DNA. Fraternal twins, since they are from separate eggs, have different DNA.
True. Each individual (except for identical twins) has a unique set of DNA that is inherited from their parents, resulting in genetic variations between different people.
Only if you are identical twins.
