新疆蒙古族对糖精和乙酰水杨酸尝味能力的分析

对710名（男328人,女382人）新疆蒙古族进行了糖精和乙酰水杨酸尝味能力的检测分析。结果表明,蒙古人群中的糖精味盲率为4.648%,没有尝味能力的隐性基因频率为0.2156,具有尝味能力的显性基因频率为0.7844,平均尝味阈值为8.009±1.34（0.108mol/L）。乙酰水杨酸的尝味阈值分布出现了非常明显的双峰一谷分布,表明该性状是单基因决定的性状,谷底7号液（3.00×10-4 mol/L）是味盲的界限,味盲的峰值在1号液(1.7×10-2mol/L),尝味者的峰值在11号液（1.25×10-5mol/L）,味盲率为90.282%,。经χ2检验,男、女性的味盲率无显著差异（P＞0.90）,表明决定乙酰水杨酸尝味能力的基因位于常染色体,对该基因的显隐性等特点尚需通过家系分析进行确定。 Abstract:The saccharin and aspirin tasting abilities have been detected and analyzed in 710 individuals (328men,382women)of Xinjiang Mongol.It is showed that the saccharin taste- blindness ratio among Mongolians was 4.648%,frequency of the recessive gene determining taste-blindness and the dominant gene determining taste ability was 0.2156,and 0.7844 respectively,and its mean testable threshold was 8.00±1.34 (0.108mol/L).Distribution of aspirin tasting threshold appeared a distinct curve with double peaks and single bottom,and demonstrated the aspirin tasting ability was a monogenic character.Solution NO.7 (3.00×10-4mol/L) at the bottom in the curve was the boundary of taste-blindness.The peak of taste-blindness was at the solution NO.1 (1.7×10-2mol/L),and the peak of tasters was at the solution NO.11 (1.25×10-5mol/L),The ratio of aspirin taste-blindness was 90.28%.The χ2 test has been used to evaluate the statistical difference in aspirin taste-blindness ratio between male and female,the result showed that there was no significant difference (P＞0.90),and the gene determining for aspirin tasting ability located on autosomes.
