no one's DNA is the same it's probaly just changing or growing in different ways

Twins who are of the opposite sex or do not look alike are fraternal twins ~ not identical. This means that at the time of their conception ~ two eggs were fertilised. In the case od identical twins, one egg is fertilised and split in half.
They may look alike, but they will never have the same fingerprints, because fingerprints are created by differences of thickness in the dermal layer. It is independent of genetics, therefore, twins will never have identical fingerprints and any similarities between twins fingerprints would merely be coincidental.
Yup. My twin is an A and I am a B (done by the military, twice to double-check). We look and talk alike. Sound alike.
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.
Sexual recombination
Yes
Yes. Fraternal twins don't look alike at all. Identical, meaning to look the same, are well, identical.
Identical twins look exactly alike.
No, no one is identical. Even "identical" twins are not exactly alike.

(Person that asked the question)-Once twins are born, and old enough to determine whether they are identical or fraternal, how do you know if they are identical, or just fraternal twins that look identical? I was just curious.
Twins don't always think alike, whether they be identical, fraternal, or even simese. It depends on there personalities, not their looks.
If they are identical then they will sorta look alike, if they are ferturnal they do ALIKE.I am a Twin so I would no!
They are identical and Nick is older by seven minutes.
Nonidentical twins Dizygotic twins (commonly known as fraternal twins, but also referred to as non-identical twins or biovular twins)
because the cheeky girls are identical twins
Fraternal. They develop from separate ova and are not genetically identical, so look different, can have different sex etc. Unlike "identical twins."
