Root tip cells of hexaploid oats Avena sativa L. were examined at mitotic metaphase, and distances between homologous as well as between non-homologous chromosomes were measured and their frequency distributions compared. Nonhomologous chromosomes were scattered at random in the cells studied. In contrast, the mean distance between homologous chromosomes was significantly shorter. There is a tendency this species. for somatic association of homologs in this species.
