Synaptinemal complex dissolves but the two homologous chromosomes in each bivalent remain joined by one or more chiasmata which represent the sites where crossing over has taken place (Fig. 10.1).

The paired chromosome formations are called bivalents. If there are more than two homologues in paired situation, they are called “multivalents”, e.g., trivalents, quadrivalents, pentavalents etc. The following changes are seen in this sub-phase; great dodgers relief pitchers

These are leptotene (boquet stage), zygotene ( zipper stage), pachytene ( tetrad stage) , diplotene and diakineis. During Zygotene, pairing of homologous chromosomes takes place.
