摘要：
The morphotypic variability in the masticatory surface of the third upper molar has been studied in six rock vole species. In total, 49 morphotypes have been identified. Based on the morphotypes identified on the left and right maxilla, epigenetic landscape models turning out to be similar have been constructed for the studied species. Each model is based on two most frequent morphotypes. The highest proportion of asymmetric animals (except Tuva voles) has exactly these morphotypes. The remaining morphotypes may be considered within the epigenetic landscape model as intermediary and as recording longer transitions between the two main morphotypes.
