Inherited diseases fall into various categories, depending on whether they involve a single gene, multiple genes, a chromosomal disorder, or mitochondrial inheritance. If one focuses just on the single gene case, one has, for example, cystic fibrosis, sickle cell anemia, hemochromatosis, and Huntington’s disease. If cloning were implemented, then – as John Roberson (1994) and Dan Brock (1998, 146) pointed out – provided that only one of the potential parents had the defective gene, a clone could be made using a cell from the one who does not suffer from the genetic defect, and the result would be a child who was free of the inheritable disease, and also genetically related to one member of the couple – something that many might find preferable to using a donor egg or donor sperm, where the resulting child would involve a genetic contribution from a third party.
