The effects of naturally occuring combinations of second and third chromosome gene arrangements of Drosophila melanogaster on two quantitative traits were partitioned into parameters of additive, dominance and interaction components of genetic variation. Development time and preadult survival of the gene arrangement genotypes were measured under four experimental conditions. Gene arrangement effects, when significant, were predominantly additive under all conditions. Experimental conditions, however, did influence gene arrangement effects. A second chromosome effect on development time was detected when amount of food or temperature was reduced, but not under optimal conditions. A third chromosome additive effect on development was observed under all experimental conditions. A consistent interaction effect between second and third chromosome gene arrangements was detected only at low temperature. Gene arrangement effects on survival were not as consistent as for development time, but also depended on experimental conditions.
对果蝇第二和第三染色体基因排列的自然组合对两个数量性状的影响，被分解为遗传变异的加性、显性和互作分量的参数。在四种实验条件下，测量了基因排列基因型的发育时间和幼体存活率。在所有条件下，当基因排列效应显著时，主要是加性的。然而，实验条件确实影响了基因排列效应。当食物量或温度降低时，第二染色体对发育时间的影响被检测到，但在最佳条件下则没有。在所有实验条件下，第三染色体对发育的加性效应都被观察到。只有在低温下，才能检测到第二和第三染色体基因排列之间一致的互作效应。基因排列对存活率的影响不如对发育时间的影响那么一致，但也取决于实验条件。
