Abstract

The karyotypes of 18 species of Malayan rats, genus Rattus Fischer, are reported. Present studies reveal that the karyotype of rats is not species-specific. The variability in diploid number (2n) within the genus Rattus is reaffirmed. A range of 36 to 52 is reported, with 2n=42 having the highest frequency. The affinity of Malayan rats is discussed on the basis of chromosomal evidence.
