✦ Synopsis

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.

The genes for human complement components C6, C7, and C9 are linked on chromosome 5. In this report we describe the physical linkage between C6 and C7 genes. DNA fragments obtained by digestion with several rare-cutting restriction enzymes were separated through pulsed field gel electrophoresis. Hyb
