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.
In nature, twins occur just after fertilization of an egg cell by a sperm cell. In. rare cases, when the resulting fertilized egg, called a zygote, tries to divide into. a two-celled embryo, the two cells separate. Each cell continues dividing on its. own, ultimately developing into a separate individual within the mother.
