Gene frequency, human population, phenylthiocarbamide, taste sensitivity, tharu tribe.

Phenylthiocarbamide's bitter taste is a genetically determined trait. The taste perception ratio and gene frequency of phenylthiocarbamide tasters compared to non-tasters are variable traits in different human populations. Several studies have reported that around 65-70% of human populations are tasters and 30–35% are non-tasters. Overall, a total of 841 Tharu tribes (506 males and 335 females) from Lakhimpur residing along the Nepal border were used for this study. The frequency of non-tasters was 25.1% and the "t" allele frequency was 0.50, while the frequency of tasters was observed to be 74.9% and the "T" allele frequency was 0.50. There was an observable but statistically insignificant (p 0.05) difference in the PTC taste sensitivity. There is limited information on the population genetics of the Tharu population of Lakhimpur Kheri district regarding taste perception. This study investigated the distribution and frequency of taster (T) and non-taster (t) alleles in the Tharu population using phenylthiocarbamide (PTC % composition is 30 mcg/taste strip). The present study was carried out to analyse the predominance of PTC taste sensitivity and allelic frequencies among the Tharu tribes of Lakhimpur Kheri.
