Abstract
The occurrence and morphology of three ultrastructural markers on meiotic chromosomes are described on the basis of three dimensional reconstructions of 29 early pachytene and 28 mid-late pachytene nuclei: 1) A condensed granular structure surrounded by a larger body of uncondensed chromatin is situated near the telomere of the short arm of bivalent 1. 2) A globoid structure with a fine granular substructure is present in the middle of the short arm of bivalent 6.3) A body of coarse granules is situated near the middle of the long arm of one of the two longest D group bivalents.
