为了研究X-灭活(Lyon，1961)对女性色盲携带者的可能影响，进行了两个实验。第一个实验的结果，与Grutzner等人的结果一样。(1976)，与Lyon(1961)假设的预测一致，即女性携带者的视网膜由色盲和正常区域的马赛克斑块组成。在第一个实验中，人们用速示镜呈现了一行和一列的彩色斑点，并要求受试者识别这些斑点的颜色。在第二个实验中，来自石原色盲测试的图板被用速示镜展示，受试者被要求识别嵌入到彩色圆点图案中的数字。这两个实验都支持里昂假说，因为女性携带者被发现比对照组受试者更难感知有色刺激的模式，它们表明，携带者扫描有色刺激的时间长短对她准确感知它们的能力起着重要作用。
Two experiments were conducted in order to investigate the possible effects of X-inactivation (Lyon, 1961) on female carriers of colorblindness. The results of the first experiment, like those of Grutzner et al. (1976), were consistent with the prediction of the Lyon (1961) hypothesis that the retinas of female carriers are composed of mosaic patches of colorblind and normal areas. In this first experiment, rows and columns of colored spots were presented tachistoscopically, and subjects were asked to identify the colors of the spots. In the second experiment, plates from the Ishihara test of colorblindness were presented tachistoscopically and subjects were asked to identify the number which was embedded in the pattern of colored dots. Both experiments support the Lyon hypothesis in that female carriers were found to have more difficulty in perceiving patterns of colored stimuli than did control subjects, and they suggest that the amount of time that a carrier has to scan colored stimuli plays an important role in her ability to accurately perceive them.
