By definition two children born to the same mother at the same time would be twins. It would be possible that they would not be twins if they were only half brothers, meaning that they shared a father but were born to two different mothers at the same time, or where they shared the same mother and father, but one was carried and born to a surrogate, or both by two separate surrogates and just happened to look very simmilar, though they would share different DNA.

If they did share the exact same DNA and also were not twins one would have to be the 'clone' or the other, meaning that a single embryo was 'conceived' from one sperm and one egg, which was cloned, and each embryo was implanted into a different woman's womb, and were born at the exact same time.

They could just be dogs or another animal that is born in a liter. They're brothers and look exactly the same, but aren't neccesarily twins.

Non-identical twins are called?

If identical twins marry identical twins could at least some of their kids look like twins having similar fingerprints?

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.

Do fraternal twins look alike?

Usually but not always. They can even be different sexes. Identical twins are fromed from one fertilized egg which splits into two and so genetically they have the same DNA and are therefore identical. Fraternal twins are formed from two separate eggs fertilized by two separate sperm cells, and are called 'twins' simply because they share the womb during their development. Otherwise, they are no more similar than normal brothers, sisters or a brother and sister.


If twins aren't identical what are they called?

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.
