概要 I3 was compared among three laboratory strains: NAG (I3 absent in 97%), TESS, and RYU (normal strains). TESS and RYU individuals had a longer distance from the upper fourth premolar to the upper third molar (P4M3), relative to palate length (PL), than NAG individuals. Specimens with oligodontia at I3 and P3 showed no difference in the ratio of P4M3 length to PL. These findings suggest that osteological factors do not account for the absence of P3 and I3. Therefore, we believe that oligodontia in S. murinus depends on odontogenetic factors. In addition, as for I3 and P3-absent, possibility related to some genes was thought about.
