HITING (1945), working on the parasitic wasp Habrobracon, developed a timing method that distinguished oocytes irradiated in the first meiotic metaphase (metaphase I) from those irradiated in the first meiotic prophase (prophase I) . She used embryo lethality of X-irradiated eggs from diploid virgins, which measured mostly dominant lethality, and found that metaphase I oocytes are approximately...
