the major difference between the variable karyotypes (2n = 40–42) and the apparently stable karyotypes (2n = 34) was that the latter has an entirely biarmed autosomal complement. The num-ber of acrocentric pairs varies from four to seven, not counting the unpaired element present in karyotypes with 2n = 40 and in one with the 2n = 41. The karyotype with 2n = 34 was characterized by two pairs of very large submetacentric chromosomes that were conspicuous not only for their size, but also for the secondary constrictions evident in one of the pairs. This karyotype also has only one pair of large subtelocentrics. In contrast, the karyotypes with 2n = 40–42 have an additional pair of large subtelomeric, but lack the two pairs of very large submetacentric. Both Robertsonian rearrangements and pericentric inversions were required to explain that karyotypic differences. The configurations of these karyotypes do not suggest supernumerary chromosome involvement.

the major differences between karyotypes 3 and 4 can be explained by either fissions or Robertsonian rearrangements. Both explanations presuppose whole-arm homologies between the chromosome set of these karyotypes, with one having been derived from the other, however, confirmation will require the analysis of banding patterns. Karyotypes from intervening populations were unknown and evidence for or against hybridization was lacking between the forms with 2n = 36 and 2n = 54.
