1. Animal Breeding
With a sufficiently high
success rate, this procedure could be of great benefit to animal breeders.
The clones possess essentially the same genetics as the animal, male or
female, from which the cells providing the nuclei were obtained that are
inserted into the enucleated eggs. In the case of sheep, the cells could
be obtained from a disease-free animal producing a luxurious coat of wool
or possessing an ideal quality of meat. In the case of cattle, the donor
cells could be obtained from
cows producing an abundant supply of milk
or animals with high quality meat. Instead of breeding champion race horses,
which dilutes the genes of the champion with the genes of the mate, clones
of the champion race horse could be produced, resulting in offspring essentially
genetically identical to the champion race horse. Such offspring should
bring very high prices.
2. Human Reproduction
If sufficient research were performed and if the procedure is not prohibited by law, it is possible that some day humans will be cloned. At this point it is not possible to make a definite prediction as to success. What might be considered potential benefits? Human cloning would permit the production of a son or daughter for a non-fertile couple. Even if the wife had no ovaries and her husband could not produce healthy sperm, the nucleus obtained either from one of the wife's cells (thus producing a female offspring) or from one of the husband's cells (thus producing a son) could be inserted into an enucleated egg obtained from another woman. The reconstituted totipotent egg could then be implanted in her uterus or the uterus of another woman (a surrogate mother) and developed to term. The offspring would be essentially identical to either the husband or the wife. Many variations of this scheme can be imagined.
