摘要: The population frequency distributions of electromorphs polymorphic loci, when ordered by electrophoretic mobility, tend strongly and significantly to be both unimodal symmetrical. Such are predicted all step-change models their generality in published data can construed as supportive the hypothesis. On other hand, unimodality symmetry might also due artifactual “unit perception” biases that affect interpretation reporting electro-phoretic data. In any case, it appears perceived highly heterogeneous.
