The spatial distributions of 3 readily identifiable chromosomes in somatic cells of monoploid barley (H. vulgare, n = x = 7), as determined by the measurements of distances between them, were compared with the theoretical random distribution. None of the 3 distributions were significantly different from the theoretical. Thus, the 3 nonhomologous chromosomes in barley do not exihibit the propensity for somatic association. The implications of these results to nonhomologous pairing observed during meiotic prophase of barley monoploids are also discussed.
