Figure 1

Electron micrographs of zebrafish meiosis. (a) Zygotene oocyte, showing 50 stretches of SC with an attachement plaque at one of each. (b) Pachytene oocyte with 24 completely paired bivalents and one bivalent unpaired for the distal half of the long arm (arrowed). (c) Pachytene spermatocyte with 25 completely paired bivalents. The prominent centromeres allowed easy reconstruction of the six breakpoints. Inset, an SC with excrescences on the long arm (arrowed). (d) Diplotene spermatocyte with 25 bivalents but little residual SC. Scale bar=10 μm.
