Abstract

Provisional maps are presented for all acrocentric bivalents and bivalent 9, according to their chromomere patterns at pachytene in the human oocyte. Each G band is subdivided into several sub-bands whose numbers varies according to the degree of chromosomal compacting. Chromomere number and sequence are in basic agreement with those observed in late prophase mitotic chromosomes. Thus, metaphase G bands of mitotic chromosomes result from progressive compressing together of smaller chromomeres whose individuality disappears as chromosomal condensation increases with progression of prophase.
