A cell created by cloning is genetically identical to the organism that donated the nuclear DNA, except for small differences such as mitochondrial DNA and any new mutations that may occur.

Quick scoop

  • In nuclear cloning, the nucleus of a body (somatic) cell is transferred into an egg cell whose own nucleus has been removed.
  • Because the nucleus carries almost all hereditary information, the resulting cell has (almost) the same genetic makeup as the DNA donor, so it is described as genetically identical to the donor.
  • A minor exception is mitochondrial DNA, which usually comes from the egg cell, meaning the clone is “nearly” but not absolutely identical at the whole‑genome level.

So, in textbook terms, the best completion is:

A cell created by cloning is genetically identical to the parent (donor) cell/organism.
