Abstract

Karyotypes of two Japanese insectivorous species, Crocidura dsinezumi chisai (2n=40, FN=52) and C. horsfieldi watasei (2n=26, FN=48), are investigated by G- and C-banding pattern analysis. Based on the G-banding patterns it is suggested that the 7 meta- or submetacentric pairs observed in C. h. watasei have been developed by the Robertsonian fusion of 10 acrocentric pairs, and also the centromere-telomere translocations between two subtelocentric and acrocentric pairs included in the C. d. chisai karyotype.
