设计和构建了2个多Y单位迷宫，这将允许评估果蝇种群趋光行为的均值和方差。以迷宫表现为标准，选择已经应用了15代。通过这种方法，已经产生了高度光正性和光负性菌株。在不同的迷宫选择的强度和限制建立。通过对选择品系和分离品系的行为分析，论证了环境和遗传因素对果蝇趋光行为的相互影响。本文讨论了实验动物群体中个体差异的必要性和趋光性研究中受控环境的重要性，特别是果蝇。
The design and construction of 2 multiple Y-unit mazes are described, which will permit the assessment of the mean and variance of phototactic behavior in Drosophila populations. Using maze performances as criteria, selection has been applied for 15 generations. By this procedure highly photopositive and photonegative strains have been produced. The strength and limits of selection in the different mazes are established. By an analysis of the behavior of the selected and unselected strains, the interaction of the environmental and genetic influences of phototactic behavior in Drosophila melanogaster is demonstrated. The necessity of recognizing individual differences in populations of experimental animals and the importance of a controlled environment in the study of photo-taxis are discussed, with particular reference to Drosophila.
