Spatial distribution of chromosomes 1 and Y in human spermatozoa.
The positions of chromosomes 1 and Y inside human spermatozoa were determined by differential staining techniques. In 85/100 cells the two chromosomes were in close contact and in association with a vacuole. This observation is in contrast to previous findings for chromosome No. 9 and the Y-chromosome whose positions do not appear to be correlated.
