Identical Twins occur when a single egg is fertilized by a single sperm to form one zygote (monozygotic) but the zygote then divides into two separate embryos. The biological mechanisms that prompt the single fertilized egg to split in two remain a mystery. The two embryos develop into foetuses sharing the same womb.
The answer to this question depends on what type of twins they are! There are two types of twins. In one case, twins can be produced when two eggs are present at the same time inside the mother, and both of these eggs get fertilized. Each of them eventually grows into a separate baby. Because each egg and each sperm started with different DNA, the babies that grow from each have different DNA.
