Chromosomal Polymorphism in Thracian Populations of Rattus rattus (Linnaeus, 1758) (Rodentia: Muridae)
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...
