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.

What helps to solve crimes because no two people have the same DNA except identical twins?

DNA analysis is a powerful tool in solving crimes because each person's DNA is unique, except for identical twins who share the same DNA. By comparing DNA evidence found at a crime scene to that of a suspect or a database, forensic analysts can link individuals to the scene and provide important evidence in legal proceedings.

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.
