prize parent cows produce embryo through sexual reproduction, individual cells are separated from the embryo (this does not harm the embryo), each of these genetically identical cells divide by mitosis to produce a mass of cells called an embryo (identical twins are formed when an embryo separates naturally), each embryo is inserted into the uterus or womb of a surrogate cow, at the end of the pregnancy each surrogate will give birth to a calf. Each calf is an identical twin and does not share any DNA with the surrogate.
