Triple-testcross experiments were used to analyze epistatic contributions to larva weight, pupa weight, pupa width and adult weight in Tribolium castaneum. Seven diverse inbred lines and the F1. produced by crossing the two tester lines were examined for indications of epistasis. Larva weight was the only trait for which no significant epistasis was detected. There was significant epistasis for pupa weight in three of the inbred lines; for pupa width in four of the inbred lines; for adult weight in five of the inbred lines. Only one inbred line and the F1 line failed to exhibit significant epistasis for any trait. Each inbred line had a unique pattern of epistasis, suggesting that a number of different loci were contributing to the detected epistasis.
三倍杂交实验被用来分析在赤拟谷盗中幼虫体重、蛹重、蛹宽和成虫体重的上位性贡献。对七种不同的近交系和由两条测验系杂交产生的 F1 进行了分析，以观察上位性的迹象。幼虫体重是唯一没有检测到显著上位性的性状。在三个近交系中，蛹重存在显著的上位性；在四个近交系中，蛹宽存在显著的上位性；在五个近交系中，成虫体重存在显著的上位性。只有一个近交系和 F1 系在任何性状上都没有表现出显著的上位性。每个近交系都有独特的上位性模式，表明有许多不同的基因座对检测到的上位性有贡献。
