Karyotypic races of the common shrew (Sorex araneus L.) from northern Poland.
Karyotypic races of the common shrew which differed with respect to the combinations of chromosome arms in certain 2-armed autosomes were distinguished in Poland. Two eastern races with the arm combination ik, and one western race with the arm combination hi in the third pair of autosomes were established. In the contact area of these chromosomal forms, the fourth karyotypic race with the arm combination hk was found.
