Meiosis in the human female

Abstract

Techniques are now available for the study of meiosis in the human female through the short term culture of oocytes from ovaries. One cell, in which 23 bivalents could be distinguished, shows interstitial chiasmata in the bivalents, in which all four strands can be distinguished. The small bivalents appear to terminalise first. The chiasma count was consistent with the number in the male.
