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.

No, identical twins have the same DNA because they come from the same egg.


What is the different of identical twin and flaternal twin?

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.


Are twins born with different DNA?

Yes EVERYBODY has different DNA even if you are identical twins.


What percent of genetic makeup is shared by 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.


Will identical twins have the same DNA-fingerprinting?

No


Do twins have the same DNA?

identical twins do. just not the same fingerprints.


Is the DNA in twins the same?

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.


Do identical twins have the same finger prints and DNA at all?

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


Who are clones fraternal twins or identical twins?

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.


No 2 people will have the same DNA except for exact twins True or False?

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.


Does my sister have the same DNA as me?

Only if you are identical twins.


Do identical twins have the same DNA?

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.
