Monozygotic [maternal] twins do have the same DNA. Hence they are identical.

In my earlier post I got the naming on the type of twin incorrect, it shouldn't have been identical. I was trying to explain that aspect in the second paragraph. My mistake.

Clones on the otherhand and have identical nuclear DNA, but are not necessarily identical because some early development processes rely on maternal genome material and not nuclear DNA, and depending on the cloning process they may have different mitochondrial DNA (mtDNA).

I assume the mitochondrial differences are due to nucleus swapping, different line of extra-nuclear heritage? ____________________________________________________________________ To know what is right and not to do it is the worst cowardice.
