Comparative restriction analysis of genomic DNA from six wood mouse species of the genus Apodemus as well as from the house mouse Mus musculus and a Norway rat Rattus norvegicus was conducted by means of AluI, TagI, Csp6I, and BglII endonucleases. The data from RFLP and UPG analyses allowed division of all the forms studied into two groups, evolutionarily young and old, including European (sylvaticus, flavicollis, and microps) and Asiatic (peninsulae, speciosis, and agrarius, together with the striped field mouse) wood mouse species, respectively. The first group is characterized by low interspecies and intragenomic RFLPs of the repeated DNA sequences, while these indices were higher in the second group. The interspecies genetic distances averaged around 1.29% within the first group, around 5.88% within the second group, and around 9.49% between the groups. The divergence of A. agrarius from the Asiatic species of wood mouse was 5.33%, twofold lower than divergence from the European species (9.17%).
