[Terminalization of chiasmata. Analysis of the phenomenon].

On the basis of my own and published data, a conclusion was made that meiotic terminalization of chiasmata, which was postulated by Darlington, does not occur. The chiasmata remain in the sites where they appear, until the disjunction of homologous chromosomes in meiotic anaphase I. The disjunction of homologues is accounted for by repulsion of the sister chromatids.
