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 main cause of fraternal and identical twins comes from conception; either two completely separate eggs can be fertilized (fraternal twins) or one fertilized egg can split into two during maturation (identical twins).o start off, let's first talk about fraternal twins, another word for this is dizygotic which means a fraternal twin happens when two separate eggs are fertilized by two separate sperm. These babies can come out because of different reasons such as hyper-ovulation (it is hereditary).
