Karyotype of the Alexandromys evoronensis animals of the chromosomal race “Argi” with 2n = 36 a GTG-banded, 2n = 36c, # 4548, male from population No. 6 b C-banded, 2n = 36a, # 3950, male from population No. 7 c NORs, 2n = 36b, male of laboratory-bred from population No. 7. Black dots mark centromere positions in three pairs of chromosomes formed by the fusion of acrocentrics of the “Evoron” chromosomal race.
