The frequency of defective colour vision was studied in two neighbouring villages in the Andes Mountains of Colombia using AO H-R-R Pseudoisochromatic plates. The frequency of the red-green colour-blindness in males is almost the same in both villages (2.36-2.53%), being similar to frequencies reported for other mestizo' populations in Latin America. In one of the communities, families in which colour-blindness occurred were wealthier (P is less than 0.05) than non-colour-blind families, but there were no significant differences by colour vision class in numbers of surviving children nor mother's marriage age. These findings are consistent with the idea that in societies at the agricultural level, colour-blindness is selectively neutral. The association of colour-blindness with higher socio-economic status is expected given the history of European conquest in the New World, and suggests that the major cause of varying rates of the defect in Latin American populations is socio-economic heterogeneity and by inference different degrees of European-Amerindian admixture.
使用AO H-R-R伪等色图对哥伦比亚安第斯山脉两个相邻村庄的色觉缺陷频率进行了研究。两个村庄男性红绿色盲的频率几乎相同（2.36%-2.53%），与拉丁美洲其他混血人群报告的频率相似。在其中一个社区，出现色盲的家庭比非色盲家庭更富有（P<0.05），但在存活子女数量和母亲结婚年龄方面，按色觉类别没有显著差异。这些发现与以下观点一致：在农业水平的社会中，色盲是选择性中性的。鉴于欧洲在新大陆的征服历史，色盲与较高社会经济地位的关联是可以预期的，这表明拉丁美洲人群中该缺陷发生率不同的主要原因是社会经济异质性，由此推断是欧洲-美洲印第安人混合程度不同。
