Abstract
Using the measures of genetic, migrational, and geographic distances, the population structure was analyzed of populations in Kamishima, Toshi, Momotori and Toba, Mie Prefecture, to clarify the population genetic relationships among these populations. In order to measure the migrational distance relationships between the populations, a new statistic based on surname distributions was adopted. The genetic distance relationships were estimated by the method of HARPENDING & JENKINS (1973) and the analysis was based on the variability in 10 blood group, serum protein and red cell enzyme systems. Further, in order to give a visual interpretation of these distance matrices, diagrams were represented based on genetic affinity and dendrograms were reconstructed based on both genetic and migrational distances. Finally, the correlations between genetic, migrational, and geographic distances separating the populations were examined.
It is concluded that half of the genetic diversity among these populations may reflect the variation caused by inter-populational migration and the remaining half may correspond to random variation.
