The ability to taste some bitter compounds is genetically determined (Snyder, 1931).Two compounds, phenylthiocarbamide (PTC) and 6-n-propylthiouracil (PROP), taste bitter to some people and are tasteless to others (Blakeslee and Fox, 1932; Fox, 1932; Fischer, 1964).In past studies assignment of PROP taster status …
WebThe ability to taste the chemical compound PTC (phenylthiocarbamide) is coded for by a single gene with two alleles. Let T stand for the allele that codes for tasting and t for the allele that codes for non-tasting. This allele exhibits complete dominance, such that heterozygotes can also taste PTC. Suppose that out of a population of 100 ...
