Somatic cell nuclear transfer can also be used to create a clonal embryo. The most likely purpose for this is to produce embryos for use in research, particularly stem cell research. This process is also called "research cloning" or "therapeutic cloning." The goal is not to create cloned human beings, but rather to harvest stem cells that can be used to study human development and to potentially treat disease. While a clonal human blastocyst has been created, stem cell lines are yet to be isolated from a clonal source
The term clone is used in horticulture to mean all descendants of a single plant, produced by vegetative reproduction or apomixis. Many horticultural plant cultivars are clones, having been derived from a single individual, multiplied by some process other than sexual reproduction
Clonal derivation exists in nature in some animal species and is referred to as parthenogenesis. An example is the "Little Fire Ant" (Wasmannia auropunctata), which is native to Central and South America but has spread throughout many tropical environments.Many people are for human cloning for many reasons. The most powerful advantage of human cloning is that defective genes would not cause any more illness in human beings. Cloning might be the cure for the most powerful diseases such as cancer, AIDS, diabetes, stroke, etc. Cloning of cell tissue can take a good cell from existing tissue and grow cloned tissue from it, therefore damaged cells can be replaced. Cloning could also help the infertile have children that are truly their own and not bein
