为了区分选择性繁殖的黑腹果蝇品系的活性和反应性的变化，在圆形跑道上连续25分钟测量了活性、非活性和对照种群的反应。拟合Y + A + B log 10 x形式的回归方程表明，两个实验群体的评分下降率均大于对照群体。对于3个种群中的任何一个，这种衰减的渐近线都不重叠。结果表明，在两个实验种群的反应性增加，但活性和非活性菌株的相似性表明，它们之间的主要表型差异是在他们的自发活动的水平。相似性是由于实验品系的遗传变异性降低。
In order to distinguish between changes in activity and reactivity in selectively bred strains of Drosophila melanogaster the response of active, inactive and control populations was measured over 25 successive min. in a circular runway. Fitting a regression equation of the form Y + A + b log10x showed that the rate of decrease in scoring was greater for both the experimental populations than for the control. The asymptotes of this decay did not overlap for any of the 3 populations. The results show an increase in reactivity in both experimental populations, but the similarity of the active and inactive strains indicated that the primary phenotypic difference between them is in terms of their level of spontaneous activity. The similarity is due to a decrease in the genetic variability of the experimental lines.
