Concordant divergence in proteins and mitochondrial DNA between two vole species in the genus Clethrionomys.

摘要: The bank vole (Clethrionomys glareolus) and the northern red-backed (C. rutilus) are two closely related species where interspecific crosses result in fertile female but sterile male offspring. Mitochondrial DNA (mtDNA) fromC. rutilus has passed barrier is found inC. glareolus from Fennoscandia. present report shows that genetic distance between species, calculated enzyme data (Nei'sD), 0.64. Isoelectric focusing of muscle proteins resolved around 55 bands, which each had 6 or 7 bands not other species. Sequence divergence mtDNA 13.9%. A comparison protein distances pairs reveals a high correlation measures, indicating differences taxa random when compared to protein-coding nuclear genes. relationship betweenClethrionomys andC. similar pairs. It also shown despite large on level it still, some cases, possible for produce hybrid females.
