The length of 44 silver-stained human autosomal pachytene complements was shown to vary from about 300 micrometer to at least 535 micrometer. The lengths of the individual 22 autosomal chromosomes of eight complements representing this interval was measured and the relative lengths calculated. For m

β¦ Synopsis
The chromosomes of twenty individuals with normal karyotypes were studied to determine the patterns of staining with the Ag--AS technique. These patterns were shown to be variable from one individual to another, but characteristic and constant within each individual. In addition, one patient with chronic lymphocytic leukemia was studied, and shown to have an Ag--AS staining pattern that was distinctly different from that of normal subjects.

The absence of silver grain precipitation on human chromosome 17, consistently observed in four patients displaying the 17p variant, supports the hypothesis that the 17p variant is a structural heteromorphism rather than translocated satellite material.
The Ag stainability of the nucleolus organizer region (NOR) was studied in the acrocentric chromosomes identified by Q banding of cultured lymphocytes in 41 karyotypically normal persons (33 males and 8 females) originating from southeast Estonia. The data obtained are compared with those establishe
