Taste sensitivity to phenylthiocarbamide found in South Sinai Bedouin tribes
The aim of this work was to study taste sensitivity to phenylthiocarbamide (PTC) amongst Bedouin tribes and compare the Bedouins with Arab and Jewish populations. Data obtained by the classic method of serial dilutions in 317 healthy male Bedouins, aged 16–70 belonging to different tribes, were examined. We discovered significant differences in chemosensitivity to PTC in the Bedouin communities. A high frequency of the t allele was documented in the Bedouin tribes of Hamada, Muzeina, anddoi:10.5671/ca.45.1.3 fatcat:pnixjtthqfdfxcytmpyk23qnmu
