Abstract

The genetic control of morphological variation (expressed as heritability) was examined by means of laboratory culture in Pileolaria pseudomilitaris [Simplaria pseudomilitaris]. Fourteen of 22 traits examined were shown to have an appreciable genetic component, after an analysis of variance among groups of full siblings. The range of variability for several traits is as large within a single sibling group as the difference between described species in the family. Comparisons among samples of P. pseudomilitaris from two habitats revealed no consistent morphological differences. A similar comparison between P. pseudomilitaris and its nearest congener, I', potswaldi, indicated significant differences for 15 of 22 traits, although ranges overlapped for all but two of these.
