Using a complex process, the nuclei of a normal egg cell is combined with an altered disease cell. This altered cell has been manipulated to have close to the same amount of chromosomes as a human sex cell (23). The slight difference in chromosome numbers does not affect these offspring in the same way as it does to only human children.
