在大、小实验群体中，分别测定了假木鸡α -淀粉酶位点等位基因的频率。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。实验群体的基因频率变化符合选择性中性假说和抽样误差导致的遗传漂变假说。
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.
