BECAUSE WHEN THEY WERE IN THE MOTHERS UTERUS< THE EGG THEY WERE IN SPLIT AND THATS HOW TWINS ARE MADE BUT SINCE THEY SPLIT THEY STILL HAVE THE SAME CHROMOSOMES AND THAT"S WHAT MAKES THEM LOOK ALIKE ---- But they are NON - identical! so the egg didn't split. There was 2 eggs! Can you explain in detail?
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.
There are differences in both DNA and fingerprints.The Claim: Identical Twins Have Identical DNA
Fraternal twins are created when 2 separate eggs are fertilized. Identical twins are created when 1 fertilized egg splits into 2. It is impossible for one identical twin to be male and the other female. Identical twins are usually the ones that look exactly alike.
MZ twins are identical twins that share 100% of the same DNA. DZ twins share only 50% of their DNA (fraternal twins). MZ twins are always the same gender, whereas DZ twins can be the same gender or one male and one female. DZM would be the male pairing of DZ twins, DZF is the female pairing, and DZO is when there is a male and a female.
the name of a graft between identical twins is called an isograft transplant, when the tissue or organ is prelevated from a donor genetically very close to the receiver, like an identical twin. Immunologically, it is closer to an autograft transplant, and some specialists even consider it an autograft transplant.
Well there are cases of identical septuplets. Like identical twins, identical septuplets are all born looking identical and of the same gender only difference is there are 7 children not 2
Nature has various safety valves. That is one of them. Conjoined Twins are identical twins with a natural connective bond, therefore they always take the same sex. Fraternal twins, like the fictional Bobbseys, can be Boy and Girl.
i am an identical twin....and my brother and i both shared the same bag when we were carried in our mothers stomachwe share many features....like the same face recognition,we also have the same gender
Acctually, they're children would not look like twins. But all of their children would look like brothers and sisters.

Identical twins are identical because they both came from the same egg. The term "Identical" is used as they look very much like each other and anybody can say that they are twins by just looking at them.
Twins don't always think alike, whether they be identical, fraternal, or even simese. It depends on there personalities, not their looks.
(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.

Non-identical twins are more like normal siblings. Identical twins have the exact same DNA, so will be very similar in appearance. Their environment will cause them to have very slight differences, such as different fingerprints and freckles.
there identical twins? but James Phelps has a scar on his chin.
