Characteristic for pachytene (Gr. pachus = dik), a stage of prophase I, are the complete pairing of the chromosomes and the lining-up of the chromomeres. Synapsis, that commonly shifts like a zip from the telomeres to the centromeres, is now at a climax. The nucleoli are often still visible at pachytene.
