- Er, to do this one would have to (1) actually observe an in vitro instance of
- monozygotic twinning as it occured; and (2) ascertain that the zygote(s) were
- female; not to mention (3) successfully implant that particular embryo &
- acheive a live delivery; as well as (4) successfully thaw & implant an embryo
- frozen for 2 decades; & (5) bring it to full-term birth.
-
- Since the techniques for human in vitro fertilization & implantation are only
- about 12 or 13 years old, & human in vitro fertilizations & implantations have
- nowhere near a 100% success rate, I guess this is still the stuff of s.f., eh?
