Methods of Plant Cloning Asexual reproduction to plants to produce duplicates from one plant specimen
4
Procedures of Animal Cloning Nuclear Transfer (Adult DNA cloning) : DNA from an egg is and with the DNA from a cell removed from an adult animal. Artificial Twinning (Embryo cloning) : One or more cells are from a fertilized embryo and encouraged to into one or more duplicate embryos.
5
Nuclear Transfer Cloning - Steps Unfertilized Eggs Collected from a donor, and nuclei removed From 2 nd Animal removed a sample cell. Nuclei from sample cell is transplanted into the egg cell. Resulting cell is cultured and a few began to divide. These early embryos implanted into a surrogate mother.
