Abstract
Changes which enhance adaptedness to the environment occur in experimental populations of Drosophila serrata which are acted upon by strong natural selection. The improvement is greater in hybrid than in single-strain populations because genetic variability is greater in the former.
摘要
在受到强烈自然选择作用的锯缘果蝇实验种群中，会出现增强对环境适应性的变化。杂种种群的适应性改善比单一种群更大，因为前者的遗传变异性更大。
