Separate before specialisation
An early animal embryo contains cells that have not yet become specialised. Cells from this embryo can be separated so that they develop into several genetically identical embryos. Each resulting embryo can then be transferred to a host mother to continue development. This process is called embryo transplantation in the specification. It begins with an embryo; it is not the same as moving a nucleus from an adult body cell.
