NEET BIOLOGY

Detailed explanation-1: -In reproductive cloning, researchers remove a mature somatic cell, such as a skin cell, from an animal that they wish to copy. They then transfer the DNA of the donor animal’s somatic cell into an egg cell, or oocyte, that has had its own DNA-containing nucleus removed.

Detailed explanation-2: -The advantages of cloning are that it helps preserve and propagate a species that has a difficult time reproducing in captivity, for example the Giant panda. Cloning provides scientists with the ability to reintroduce genes into a wild population after they have been lost.

Detailed explanation-3: -Scientists usually have a poor understanding of endangered animals’ reproductive physiology, which makes it too risky to extract a sufficient number of eggs from that species or rely on females of that species to give birth to clones. Legal protections sometimes preclude threatened species from such procedures as well.
