The genetic relationships of two subspecies of striped field mice, Apodemus agrarius coreae and Apodemus agrarius chejuensis
Article Abstract:
The genetic relationships of two subspecies of striped field mice of Korea are discussed. The two species, Apodemus agrarius coreae and Apodemus agrarius chejuensis, are morphologically distinct. A. agrarius coreae was found to have more genetic diversity than the other species. Data do not support the concept that the two morphotypes are two species. The two morphotypes do not share mitochondrial haplotypes. Likely little gene flow between the two exists. The subspecies might have been separated at the time of separation of islands from the mainland. Wan Island A. agrarius coreae with large body size cluster with the large-bodied A. agrarius chejuensis based on phylogenetic analysis.

Silent ribosomal cistrons are located at the pairing segment of the postreductional sex chromosomes of Apodemus sylvaticus (Rodentia, Muridae)
Article Abstract:
Silent ribosomal cistrons have been found to be at the pairing segment of the postreductional sex chromosomes of Apodemus sylvaticus (Rodentia, Muridae). The karyotype of the species was analyzed by G- and C-banding, Ag-nucleolar-organizer regions (NOR)-staining and in situ hydridization, with special attention to sex chromosomes.

B chromosomes and developmental homeostasis in the yellow-necked mouse, Apodemus flavicollis (Rodentia, Mammalia): effects on nonmetric traits
Article Abstract:
The analysis of B chromosomes on developmental homeostasis in the yellow-necked mouse, Apodemus flavicollis (Rodentia, Mammalia) is detailed. The carriers of B chromosome react differently to environmental changes than do on non-carriers and inorder to examine the effects of Bs on development stability three groups were formed.
