Mammal Study
Abstract
Abstract.
Karyotypes of Dremomys pernyi from Kanding, Sichuan Province, China and D. pyrrhomerus from Nanling, Guangdong Province, China were examined. The karyotype of D. pernyi was of 2n = 40 and FNa = 72, while that of D. pyrrhomerus was of 2n = 38 and FNa = 70. Karyotype of D. pernyi from Kanding was different in 2n and FNa from reported karyotype of conspecific population from Taiwan, and it is suggested that the Taiwan population represents a distinct species D. owstoni from D. pernyi. The difference between karyotypes of D. pernyi and D. pyrrhomerus may involve at least a Robertsonian rearrangement and a heterochromatin addition.
