  1. aClassification according to Dos Santos Guerra [15]: m, metacentric; sm, submetacentric; a, acrocentric chromosome pair
  2. bintTS, interstitial telomeric signal; AT-rb, AT-rich band; NOR, cluster of ribosomal DNA
  3. *Significant difference (P < 0.05) from the neighbour chromosome of the same triplet
