Description

The events of meiosis I in a living insect spermatocyte beginning at metaphase with meiotic bivalents at the spindle equator followed by anaphase , segregation of bivalents to the spindle poles and the near completion of cytokinesis. Testes from the Crane fly Nephrotoma suturalis were observed with time-lapse polarization using a Nikon Microphot SA, equipped for liquid crystal polarized light microscopy (LC-PolScope, CRi, Woburn Massachusetts) 60x/1.4 PlanApo oil immersion objective, 1.4 NA oil imm. condenser, with 1.5x zoom lens. Image acquisition and processing Camera: Images captured every 60 sec over 90 min by a QImaging Retiga EXi CCD camera. Raw images were processed using a 5-frame algorithm (Shribak and Oldenbourg, 2003). Movie images represent computed retardance as gray values ranging from 0 nm retardance (black) to 2 nm retardance or higher (white).
