PATHOLOGY

Detailed explanation-1: -Identical twins have two biological parents, while a clone has just one genetic host. Therefore clones may have one gestational mother and one or more social parents.

Detailed explanation-2: -Natural clones, also known as identical twins, occur in humans and other mammals. These twins are produced when a fertilized egg splits, creating two or more embryos that carry almost identical DNA. Identical twins have nearly the same genetic makeup as each other, but they are genetically different from either parent.

Detailed explanation-3: -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-4: -There are two ways to make an exact genetic copy of an organism in a lab: artificial embryo twinning and somatic cell nuclear transfer.
