本文描述了一种检测群体加性、显性和上位性变异的方法，方法是将该群体的雄性与两个自交系l1和L2及其F1杂交。无论该群体的遗传构成如何，该方法都可以检测出l1和l2不同的位点的显性和上位性。如果未检测到上位性，并且l1和l2是极高和极低的选择系，该方法还可以以相同的精度估计加性和显性成分，也可以估计平均显性成分。
A method is described of detecting additive, dominance and epistatic variation in a population, by crossing males from this population to two inbred lines, L1and L2, and their F1. Irrespective of the genetic constitution of this population, the method will detect dominance and epistasis for those loci for which L1and L2differ. Provided that no epistasis is detected and that L1and L2are extreme high and low selection lines, the method also allows estimation of additive and dominance components with equal precision and also estimation of average dominance.
