“Davison cites as evidence supporting his scheme: (1) examples of naturally occurring or induced parthenogenesis in which it is perceived that the second meiotic division does not occur, although the authors cited do not necessarily agree with this interpretation (see Olsen, 1996); (2) the notion (which seems to be false) that human female meiosis is arrested for many years at metaphase II (modern accounts generally place the normal arrest a late prophase I); and, most importantly, (3) the reports and interpretations of Cleveland (1947) on chromosome behavior in certain flagellate protozoa.”
