Phenylthiourea (PTC) taste sensitivity thresholds have been measured for 2,013 Nigerians using a modified sorting technique. The frequency of non-tasters was observed to be 12.5% and the t gene frequency was 0.354. There was a significant difference between the sexes at the 0.01 level for the overall population. However, when the data are analyzed according to the geographical origin of the subject, the sex difference is found only in one of three geographical regions. Also, there may be geographical influences on PTC taste sensitivity, although this was not statistically significant. The estimates reported in this population differ considerably from some of the previously published estimates for black populations.
采用改良的分类技术，对2013名尼日利亚人进行了苯硫脲（PTC）味觉敏感度阈值测定。观察到非尝味者的频率为12.5%，t基因频率为0.354。总体人群中，两性在0.01水平上存在显著差异。然而，当根据受试者的地理来源分析数据时，仅在三个地理区域之一发现了性别差异。此外，虽然这在统计学上不显著，但PTC味觉敏感度可能存在地理影响。该人群报告的估计值与之前发表的一些黑人人群估计值有很大差异。
