Mammal cloning is when a mature somatic cell is removed by researchers from an animal that they wish to produce with genetically the same information as the parents. The purpose is to produce a clone with the same genetic material as the individual from which the genetic material is taken from. They use different techniques for mammal cloning. The techniques used foe mammal cloning are embryo splitting and somatic cell nuclear transfer.
Embryo splitting is used in sheep for effective traits such as milk productivity, meat and wool. Embryo splitting is a successful in farm animals for producing genetically the same embryo and animal. It’s possible that embryo splitting increases livestock numbers quickly and reliable traits. During pregnancies …show more content…
The unfertilised egg was from a Scottish blackface ewe. The nucleus is then put in a reproductive cell which is from the donor sheep. The udder cell and the nucleus from the egg cell are fused together using an electric pulse. A second electric pulse then activates cellular activity and starts mitotic cell division. It also starts the development of the cell. The embryo is then implanted into another Scottish black ewe after six days and after the pregnancy, dolly the cloned Finn Dorset lamb was born.
Telomeric changes: Every time DNA is copied, it shrinks. It shrinks because as we age, the DNA divides and divides so many times but in egg and sperm cells, it is “immortal” because an enzyme called telomerase adds more to the end every time. But in somatic cells divide a lot slower. Somatic cells only divide to replace damaged cells which is why the divide a lot slower. Dolly the sheep showed Telomeric changes and is why she started to get sicker and sicker but she is the only cloned animal to show this implication. - …show more content…
Even though the meat has been declared safe to consume and is being sold in supermarkets. They do not know what type of “adverse effects of cloning to surrogate animals as well as to the clones themselves” could be present in the meat as scientist would not know. The procedure also causes animals to suffer. Animals could be the surrogate mother more than once and it has to go through the procedure of having an egg planted in her. Also of an egg being removed. it interferes with evolution of species. Traits are lost as a specie adapts to a certain environment as that allele become more favourable and it increase the chance of survival. If species are cloned to be identically the same as another, then they will not be able to adapt to the environment naturally anymore. They will have the genetic material to suit pre- determined environments and will not carry genetic information from both parents. They will have a template of genetic information. Over time species that have been subjected to genetic manipulation would lose its innate ability to
