title: On the ordered arrangement of the haploid complement in radial metaphases of secondary meiocytes of male grasshoppers, Euchorthippus pulvinatus gallicus.
abstract: Five hundred and ninety-three radial metaphase II cells from the male grasshopper, Euchorthippus pulvinatus gallicus, were analyzed to ascertain whether chromosomes in the haploid complement were in a fixed order. As an a posteriori hypothesis, the most probable original order of chromosomes in the metaphases was determined. The genetical significance of a suprachromosomal organization is discussed.
