| Abstract: | The chromosomes of five Crocidura species have been studied by means of routine, G-, C- and Ag NOR-banding techniques. The karyotypes of the species with 2n = 40, i.e. C. gueldenstaedtii, C. suaveolens and C. sibirica, are identical. Short arms of the Y-chromosome of C. sibirica are larger. The karyotypes of C. leucodon (2n = 28) and C. zarudnyi (2n = 22) could be obtained as a result of tandem and centric fusion and pericentric inversions. Small amounts of heterochromatin were detected in autosomes of the species investigated. The Y-chromosomes are completely heterochromatic. Four NOR-bearing pairs are detected in the species investigated. |
