Abstract: | Summary The graphical technique devised bySmith andFretwell (1974) to construct a model of the optimal offspring size was applied to the case where disruptive selection might work on
offspring size. On this basis, a possible case of speciation in freshwater gobies characterized by egg-size difference was
discussed. |
