Cloning is the process of creating genetically identical organisms. One simple method of cloning is called artificial embryo twinning. In this process, an early stage embryo is separated into two groups of cells. Each group of cells is then allowed to develop. The embryos are then implanted into the surrogate mother. Each embryo is genetically identical to the other. Some pregnancies in humans have a similar result. Explain how identical twins are formed.  Compare and contrast the natural formation of identical twins to the artificial embryo twinning process.  Explain how the formation of identical twins or the process of artificial embryo twinning differs from the formation of fraternal twins.

Cloning is the process of creating genetically identical organisms. One simple method of cloning is called artificial embryo twinning. In this process, an early stage embryo is separated into two groups of cells. Each group of cells is then allowed to develop. The embryos are then implanted into the surrogate mother. Each embryo is genetically identical to the other.

Some pregnancies in humans have a similar result.
