The Pros And Cons Of Cloning Animals

Cloning animals has been around for the last century, and with each year, becomes bigger and possibly more controversial as researchers discover new advances in the field. In 1903, the word clone was developed by Herbert Webber and his understanding of the word was taking a cell from a sexually produced ancestor and creating a group of cells asexually. In the 1950’s, newts and frogs were cloned by the first successful nuclear transfers from adult donor cells. Nuclear transfers are the process of taking the nucleus out of the egg from the recipient cell from the frog or newt and fusing the adult donor cell into the egg cell. The first somatic nuclear transfer was achieved to clone frogs in 1977, which means using an adult donor cell of a somatic cell from any part of the body. The most successful story of a cloned animal is Dolly the sheep. Dolly was created in 1996 and is the first sheep

Cloning has been perfected over the years by transferring a foreign nucleus into a surrogate mother’s egg cell. Techniques like cloning are very useful to animals and understanding more about the process of sexual production. Many animals are being cloned with foreign nuclei with antibodies that fight against diseases that may be detrimental to the animal, and hopefully from there on out, destroying that typical disease in the further offspring of that animal. This can also be useful for studies in destroying other diseases in animals and in humans as well. It is also beneficial for the study of creating animal organs into donors for human transplants. Cloning can also be the solution for endangered and rare species. By freezing eggs and somatic cells that contain the full set of DNA, endangered species may be able to reproduce into larger numbers to bring back numbers for the species, eliminating the chance of extinction (“Animal
