For the first time, the originality of karyotypes of the following small rodents of the Issyk-Kul and Sokuluk Districts was studied: Diploid set of chromosomes of the Meriones tamariscinus of the Issyk-Kul population 2n=40. Number of arms of autosomes NFa=74. 38 autosomes consist of 4 groups: 14 (M) + 10 (Sm) + 12 (St) + 2 (A) + X (M) + Y (M). The stability of karyotypes of the tamarisk gerbil of the Issyk-Kul population was revealed. The diploid set of chromosomes of the Apodemus sylvaticus of the Issyk-Kul population 2n=48. Number of arms of autosomes NFa=68. 46 autosomes consist of the following groups: 8(M)+14(St)+24(A)+X(M)+Y(M). Spatial-biotypic chromosomal polymorphism of wood mouse karyotypes of the Issyk-Kul population was revealed. The diploid set of chromosomes of the Mus musculus of the Issyk-Kul and Sokuluk populations 2n=40. Number of arms of autosomes NFa=38. 38 autosomes are made up of acrocentric chromosomes. The sex chromosomes are made up of acrocentric chromosomes that differ in size. The stability of the karyotypes of the domestic mouse of the Issyk-Kul and Sokuluk populations was revealed. The diploid set of chromosomes of the Dryomys nitedula of the Issyk-Kul population is 2n=48. The number of arms of autosomes is NFa = 90. The chromosome set consists of four groups of chromosomes: 16 (M) + 18 (Sm) + 10 (St) + 2 (A) + X (Sm) + X (Sm). Spatial-biotypic chromosomal polymorphism of karyotypes of forest dormouse of the Issyk-Kul population was revealed. The karyotype of the gray hamster is described for the first time. The karyotype of the gray hamster Cricetulus migratorius of the Sokuluk population was described for the first time: 2n=22, NF=44, 10(M)+2(Sm)+10(St); no sex chromosomes were found. When comparing karyotypes, isolated micropopulations of this species, spatial-biotypic chromosomal polymorphism was determined according to the morphology of autosomes of the diploid set of chromosomes.
