PATHOLOGY

Detailed explanation-1: -Identical twins are not exactly genetically the same, new research shows. Scientists in Iceland sequenced DNA from 387 pairs of identical twins-those derived from a single fertilized egg-as well as from their parents, children and spouses.

Detailed explanation-2: -Clones are organisms that are exact genetic copies. Every single bit of their DNA is identical. Clones can happen naturally-identical twins are just one of many examples.

Detailed explanation-3: -Even though identical twins do share a significant amount of similar DNA, there are clear genetic mutations between each member, proving that they’re not carbon copies of each other.

Detailed explanation-4: -clone, also spelled clon, cell or organism that is genetically identical to the original cell or organism from which it is derived.

Detailed explanation-5: -Though fraternal twins are together even in the womb, they are as genetically alike as any other normal brother and sister. That is, they don’t necessarily share the exact same features as their twin, like most identical twins do.
