The karyotype with 62 chromosomes contains an additional pair of small acrocentric chromosomes and it was only found in the polymorphic sample from Madaba.
Herein, chromosome alterations as pericentric inversions support the reported karyotype structure due to the significant alterations that occurred in the metacentric and acrocentric chromosomes.
