在雄性翅型二型性的研究中，豌豆蚜Acyrthosiphon pisum（Harris）的克隆在一个地点的两个季节内收集了五次，并从北美大平原地区的其他三个纬度各收集了一次。当在20 ℃下经历短光周期（L14：D10或L13：D11）时，所有克隆都产生了一些雄性。根据它们产生的雄性形态，存在三种不同的克隆类型（无翅的;有翅的;无翅和有翅的比例相等），这为二型性的遗传基础提供了证据。仅产生无翅雄性的克隆的相对频率在地理上不同，提供了一些证据来支持种群在大平原地区不是全交配的假设。
In a study of male alary dimorphism, clones of pea aphid, Acyrthosiphon pisum (Harris), were collected five times over two seasons in one location and once each from three other latitudes in the Great Plains region of North America. All clones produced some males when subjected to a short photoperiod (L14:D10 or L13:D11) at 20.degree.C. The presence of three distinct classes of clones based on the morph of males they produced (apterous only; alate only; apterous and alate in equal proportions) provides evidence for a genetic basis for the dimorphism. the relative frequencies of clones producing only apterous males varied geographically, providing some evidence to support the hypothesis that populations are not panmictic over the Great Plains region.
