本文将鳞翅目翅型变异的遗传研究与发育机制的实验研究结合起来。描述了热带蝴蝶双环蝶的研究。本工作包括人工选择具有不同翅眼斑图案的品系，然后在品系上进行嫁接实验，从发育机制方面研究表型和遗传差异。这些结果被用来展示这种翅膀模式的进化限制可能与发育组织有关。眼点模式可以设想为一组发育同源物；一个共同的发育机制与一个涉及高遗传相关性的数量遗传系统有关。然而，个别基因只影响眼点的子集，从而解除眼点的相互依赖性，可能在进化变化中很重要。假设的进化约束说明了在其他种类的双翼目中发现的翅膀图案的差异。
This paper integrates genetical studies of variation in the wing patterns of Lepidoptera with experimental investigations of developmental mechanisms. Research on the tropical butterfly, Bicyclus anynana, is described. This work includes artificial selection of lines with different patterns of wing eyespots followed by grafting experiments on the lines to examine the phenotypic and genetic differences in terms of developmental mechanisms. The results are used to show how constraints on the evolution of this wing pattern may be related to the developmental organisation. The eyespot pattern can be envisaged as a set of developmental homologues; a common developmental mechanism is associated with a quantitative genetic system involving high genetic correlations. However, individual genes which influence only subsets of the eyespots, thus uncoupling the interdependence of the eyespots, may be important in evolutionary change. The postulated evolutionary constraints are illustrated with respect to differences in wing pattern found among other species of Bicyclus.
