Associations between specific bivalents in pachytene nuclear squashs from 2n = 40 spermatocytes. a, b, and c: The bivalents 16 (red) and 17 (green) appear identified by FISH and specific probes. a’, b’ and c’: Same nuclei counterstained with DAPI; a”, b” and c”: Representation of the painted bivalents 16 and 17 and the DAPI heterochromatin of the all bivalents. In the nucleus a”, the bivalent 16 through the heterochromatin is associated with 5 bivalents while the bivalent 17 is single; In the nucleus b”, the bivalent 16 as the bivalent 17 are independently associated with other 2 bivalents; in the nucleus c”, both bivalents 16 and 17 are associated with each other and with two more bivalents through their heterochromatins.
