In cut paraffin preparations the diakinesis chromosomes from meiosis in mouse spermatocytes were found to be regularly interconnected by double structures. At prometaphase, the chromosomes are drawn together and, at metaphase I, they are clumped together, having acquired a sticky appearance and being clearly interconnected. After the anaphase I separation, the chromosomes in both groups move to the poles and are interconnected. Similar observations were made after acetic‐ethanol as well as Navashin fixations, which makes it very unlikely that the interchromosomal connections are fixation artefacts.
