Chromosomal Polymorphism In Thracian Populations Of Rattus Rattus (Linnaeus, 1758) (Rodentia: Muridae), Tolga Kankiliç, Nuri̇ Yi̇ği̇t, Teoman Kankiliç
Turkish Journal of Zoology
The black rat (Rattus rattus L.) from Thrace is an Oceanian type (2n = 38). Chromosomal analyses show that a polymorphism occurs in chromosome pairs no. 9, 10, and 13 due to pericentric inversions. In the studied populations, the frequencies of homozygous and heterozygous individuals did not differ from the Hardy-Weinberg equilibrium for chromosome pair no. 13. In both Gelibolu and Pınarhisar populations of R. rattus, a polymorphism due to the supernumerary B-chromosome was found. The R. rattus karyotype with supernumerary chromosomes is reported here for the first time in Turkey. The number of diploid chromosomes are 2n = 38, …
