    • 1939, B.R. Nebel, “Chromosome Structure” in the Botanical Review V, № 11 (Chromosome Structure, November 1939), page 586:
      Thus the condition of quadruplicate tetrasomy, triplicate hexasomy, in the apple, and probably several other data of the literature would deserve a statistical treatment according to Propach’s procedure before attaining classical significance.
    • 2007, Thomas Liehr et al., “Small supernumerary marker chromosomes (sSMC) in humans; are there B chromosomes hidden among them?” in Molecular Cytogenetics I, № 12 (2008), page 2 of 7:
      sSMC are scientifically interesting due to their still not completely understood mode of formation, karyotypic evolution and the fact, that their presence may lead to chromosomal imbalances (partial tri-, tetra- or hexasomies) without detectable clinical consequences.
