Abstract
The frequencies of alleles at the alpha-Amylase locus of D. pseudoobscura were followed in both large and small experimental populations. No evidence for balancing or directional selection was found, although our ability to detect weak selection is limited. The gene frequency changes in our experimental populations were consistent with the hypothesis of selective neutrality and genetic drift due to sampling error.
摘要
在大、小规模实验种群中都追踪了 D. pseudoobscura 中α-淀粉酶基因座等位基因的频率。虽然我们检测弱选择的能力有限，但没有发现平衡或定向选择的证据。我们实验种群中基因频率的变化与选择性中性和由于抽样误差导致遗传漂变的假设一致。
