Detailed explanation-1: -How are animals cloned? 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: -Scientists extract somatic cells (most commonly skin cells) that contain intact DNA from a “donor” dog (the dog to be cloned) and culture these cells in their lab. Then, scientists extract unfertilized eggs from a female dog and remove the nucleus from the egg, which erases that dog’s DNA from the eggs.

Detailed explanation-3: -Artificial cloning technologies have been around for much longer than Dolly, though. There are two ways to make an exact genetic copy of an organism in a lab: artificial embryo twinning and somatic cell nuclear transfer.

Detailed explanation-4: -Myth: Clones are always identical in looks. They have the same genes, but look a little different. That’s because of the way those genes are expressed-that is, how the information in that gene is seen in the actual animal.

Detailed explanation-5: -If I Clone My Pet, How Similar Will The Clone Be To My Original Pet? The clone and your original animal will be genetically identical, they will share the exact same DNA, and will therefore be a full genetic twin to your original pet.
