Karyotypes of Three Species of Rats from Hong Kong and Thailand (Muridae, genus Rattus Fischer)

The chromosomes of wild rats are poorly investigated. Most studies have been confined to Rattus norvegicus albino, most recently reviewed by Robinson (1965). Makino (1942, 1943) studied the chromosomes of 5 species of Asiatic rats with old testis-section methods-R. norvegicus, R. rattus, R. losea, R...

Description
Summary:The chromosomes of wild rats are poorly investigated. Most studies have been confined to Rattus norvegicus albino, most recently reviewed by Robinson (1965). Makino (1942, 1943) studied the chromosomes of 5 species of Asiatic rats with old testis-section methods-R. norvegicus, R. rattus, R. losea, R. fulvescens coxinga, and R. confucianus culturatus. Recently, Huang (1968) studied the chromosomes of Rattus (Mastomys) natalensis from Africa, and Yong (1968a) reported the karyotypes of 4 Malayan rats-R. bowersii, R. muelleri, R. edwardsi, and R. sabanus.The present paper deals with the chromosomes of 3 species of Asiatic rats, Rattus rattus sladeni (Anderson) and Rattus huang (Bonhote) from Hong Kong, and Rattus berdmorei (Blyth) from Thailand.
