在4个温度下，对热带干湿季节蝴蝶Bcyclus anynana的幼虫发育时间(塑料)、蛹重(少塑料)和两种翼型特征：季节性(塑料)和热型(塑料)进行了遗传相关(Rg)的测定。季节形式的RGS较弱，使其在不同季节之间相对独立。体重的RGS介于热力和季节性之间。阴性的RGS存在于发展中。发育时间的反应标准在中等温度下明显交叉，而其他的则不是。这意味着，在一个季节选择快速种植者在另一个季节会产生相反的效果。重量和其他性状之间的RGS在温度下保持不变，发育和热形态之间的相关性也是如此。发育与季节形态、温度形态与季节形态的相关性均表现出明显的温度变化。反应规范证实并澄清了这些体征变化。发育的符号变化--季节形式可能反映了潜在的生理过程。热型-季候型的符号变化可能是由于不同季节的权衡所致。
Genetic correlations (rg) within and across environments, were determined in the tropical, dry-wet seasonal polyphenic butterfly Bicyclus anynana, over four temperatures, for larval DEVELOPMENT time (plastic), pupal WEIGHT (less plastic) and two wing pattern characters: SEASONAL FORM (plastic) and THERMAL FORM (less plastic). The rgs for SEASONAL FORM were weak, making it relatively independent across seasons. The rgs for WEIGHT were intermediate between THERMAL and SEASONAL FORM. Negative rgs were present for DEVELOPMENT. The reaction norms for DEVELOPMENT time clearly crossed at an intermediate temperature, whereas the others did not. This implies that selection for fast growers in one season has an opposite effect in the other season. rgs between WEIGHT and the other characters remained constant over temperatures, as did the correlation between DEVELOPMENT and THERMAL FORM. Both the correlation between DEVELOPMENT and SEASONAL FORM and between THERMAL FORM and SEASONAL FORM showed a sign change across temperatures. Reaction norms confirmed and clarified these sign changes. The sign change for DEVELOPMENT-SEASONAL FORM might reflect underlying physiological processes. The sign change for THERMAL FORM-SEASONAL FORM might be caused by different trade-offs in the different seasons.
