Your cloned livestock animal is a genetic twin to the original cow, lamb, goat or pig. They will be the same sex, the same color and may have the same mannerisms as the original but that does not mean they will be an “exact” replica. For example, the spot pattern on a spotted cloned animal, although very similar, may vary due to migration of the melanoblasts that cause coat color. You will also find this in identical twins that are not cloned animals. In the photos illustrated below, the genetic donor on the left and the cloned heifer on the right, were taken at roughly the same age. You can see that although both animals are black and white, the spot pattern does vary.
