Figure 1

Views of chromosome pairing during meiosis (metaphase I) and their diagrammatic illustration. A - Borneo: the plate represents 4 monovalents (I), 6 bivalents (II) and one hexavalent (VI). The hexavalent is the result of association of three bivalents likely by their distal segments. B - P. Lilin: The plate shows 1 monovalent, 9 bivalents and 1 trivalent displaying a Y shape. This pattern suggests a connection point located in the proximal position.
