Whether the cloning of dogs using nuclei from cells of a pet will develop clones identical to the original pet. Concept introduction : Reproductive cloning refers to the production of genetically identical version of an existing organism. This is done through “somatic cell nuclear transfer”. The nucleus of an egg is replaced with nucleus of somatic body cell (differentiated cell) known as donor nucleus. This is implanted into surrogate mother where the embryo develops into so-called clone. The somatic cell used for this procedure is a differentiated body cell.

Although a number of different animals have been successfully cloned, the process of creating cloned animals is very inefficient. Typically, only about 0.1% to 3% of attempts result in a live-born animal. What might be some of the reasons for this low rate of success?

For each of the following scenarios, indicate YES (it is cloning) or NO (it is not cloning). 6. ___________ Sperm taken from a male goat is combined with a female's egg in a petri dish. The resulting embryo is implanted into the female's uterus to develop 7. ___________ A sheep embryo, composed of 16 cells, is removed from the mother's uterus and separated into individual cells. Each cell is allowed to multiply, creating 16 separate embryos, which are then implanted in different female sheep to develop to maturity. 8. ___________ A cow with many desirable traits is stimulated with hormones to produce a number of egg cells. Each of these eggs is fertilized and implanted into a surrogate mother. 9. ___________ Cell nuclei from a recently deceased dog are placed into enucleated egg cells from another female dog. These egg cells are then placed into the uterus of an additional female surrogate dog, where it grows into a puppy.
