When the egg and sperm combine, the combination is called a zygote. If the zygote splits into two separate parts, each part develops into an individual embryo. Because the two embryos are the result of a single egg-sperm combination, they have the same genetic origins; the same DNA. Thus, identical twins are formed.
Faternal twins are the result of two eggs fertilized by two separate sperm. Generally only one egg is available for fertilization, but if two eggs are released, they each could be fertilized producing two zygote.
