Abstract
Cytogenetic analysis revealed that naked mole-rat populations across whole species distribution range possess an identical chromosomal set (2N = 60; NF = 100) despite significant differences in mtDNA. Supposed chromosomal stability of this eusocial species is considered as a factor contributing to maintaining the genetic variability.
