Summary The structure and behavior of XY bivalent in mice is discussed. The view that XY bivalent in pachytene is embedded within the sex vesicle was fully confirmed. X and Y are paired end-to-end by a nonchiasmatic connection, which is established already in pachytene and persists until first meiotic metaphase. The pachytene complement in mice consists of 19 rod-shaped autosomal bivalents and the XY bivalent embedded within the sex vesicle. A satisfactory identification of individual autosomes in male pachytene has not been found possible.
