The karyotype of R. lutreolus is indistinguishable from that of R. rattus with 42 chromosomes (Folio 475). In R. tunneyi, autosome pair No. 9 possesses a short second arm, probably representing a pericentric inversion. Individuals have been found to have 2n=43 (with an extra B chromosome) and 2n=41 (a fusion between chromosomes 2 and 5.
