Phenylthiocarbamide (PTC) taste thresholds were determined in 100 nuclear families using the complete sorting test. Segregation analysis using the mixed model suggested that the variability in PTC thresholds is controlled by a major locus with incomplete dominance as well as by a multifactorial comp

โฆ Synopsis
Complex segregation analysis reveals no evidence for incomplete dominance, polygenic variation, or an effect of family environment on PTC sensitivity. Estimates of gene frequency and displacement from a phenotypic trichotomy agree closely with conventional values for the the dichotomy of tasters vs. nontasters.
