Fig. 6. Female meiosis in cnn mutants. Oocytes derived from cnn mothers were fixed and stained for tubulin. (A) Anaphase I: the meiotic spindle is organized as in wild type. (B) Prometaphase II: the peripheral MT network has dismantled and the inner poles of the twin spindles start to organize. (C) Early metaphase II: a faint central aster (arrow) is visible between the twin spindles. (D) Early anaphase II and (E,F) telophase II: the central aster becomes hardly detectable (arrows), however, a distinct sperm aster is present (arrowhead, F), although diminutive compared to that in the wild-type. (G) Example of twin anaphase II spindles not properly spaced and rather abnormal in shape. Bars, 2.5 µm in A-E,G and 3.5 µm in F.
