ABSTRACT. A DAPI-banding technique was used to characterise the individual patterns of each chromosome of the Novosibirsk race of the common shrew (Sorex araneus) which has become a model for comparative gene mapping. In order to outline the main identifying characteristics of the individual chromosomes and to make comparisons to previously published G-banded karyotypes, we analysed DAPI-banded chromosomes with different degrees of condensation. On the basis of this analysis we constructed idiograms of chromosomes at a 300 band stage of resolution.
KEY WORDS: Sorex araneus, common shrew, chromosomes, DAPI banding.
