PATHOLOGY

Detailed explanation-1: -Dolly the Sheep was created using a cloning method called Somatic Cell Nuclear Transfer or SCNT. In SCNT, the nucleus of an egg cell is removed and replaced with the nucleus of a donor adult cell.

Detailed explanation-2: -Clones contain identical sets of genetic material in the nucleus-the compartment that contains the chromosomes-of every cell in their bodies. Thus, cells from two clones have the same DNA and the same genes in their nuclei.

Detailed explanation-3: -The egg cell has had its nucleus removed so that it will read and duplicate the DNA of the donor cell.

Detailed explanation-4: -Somatic Cell Nucleus Transfer (the most common technique used to clone animals) has however also produced healthy cattle and pig clones, and healthy offspring, that are similar to their conventional counterparts based on parameters such as physiological characteristics, demeanour and clinical status.

Detailed explanation-5: -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.
