[Analysis of saccharin and aspirin tasting ability among Mongolians of Xinjiang].
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 (3.00x10(-4)mol/L) at the bottom in the curve was the boundary of taste-blindness. The peak of taste-blindness was at the solution NO.1 (1.7x10(-2)mol/L), and the peak of tasters was at the solution NO.11 (1.25x10(-5)mol/L), The ratio of aspirin taste-blindness was 90.28%. The chi2 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.
