Variation of Adh-F allele frequency in seven regions of North and South America, Eurasia, Africa, and Australia was analyzed on the basis of published data. In six regions, regression of Adh-F frequency on latitude was positive; in four regions, slopes of the regression curves were identical. Regression on the average lowest temperature of the coldest month was negative in six regions. No definite trends in regression on the highest temperature of the hottest month and on rainfall in the most humid month and the driest months were found. Geographic differentiation of populations was independent of climatic parameters. Examination of variation in various climatic zones revealed that tropical populations were distinctly different from those from other climatic zones. No climatic differentiation of fixation index FST was detected. These results indicate that Adh polymorphism is maintained by natural selection.
基于已发表的数据，分析了北美和南美、欧亚大陆、非洲及澳大利亚七个地区乙醇脱氢酶F（Adh-F）等位基因频率的变化。在六个地区，Adh-F频率与纬度呈正相关；在四个地区，回归曲线的斜率相同。在六个地区，与最冷月平均最低温度的回归呈负相关。未发现与最热月最高温度、最湿润月和最干燥月降雨量的回归有明确趋势。种群的地理分化与气候参数无关。对不同气候带变异的研究表明，热带种群与其他气候带的种群明显不同。未检测到固定指数FST的气候分化。这些结果表明，Adh多态性是由自然选择维持的。
