Fig. 6. Female meiosis in asp^dd1. DNA is stained red and microtubules are green. (A) This field shows the telophase spindle of meiosis I (arrowhead) and the male pronucleus with associated sperm aster (arrow). (B) Telophase of meiosis II (arrowhead). Unlike wild type, the sperm aster remains diminutive (arrow). (C) Dissociation of duplicated centrosomes from the male pronucleus (arrow). (D) This field shows polar bodies with condensed chromosomes (large arrow), and three haploid anastral mitotic spindles carrying DNA derived from the male pronucleus (arrows). There are also four independent asters of microtubules (arrowheads) derived from the sperm aster that has dissociated from the spindle.
