Genetically determined (in)sensitivity of bitter PTC taste is biochemical, physiological, sensory, subjective individual quality of human. These characteristics are determined on subjective sensory of biochemical and physiological characteristics of each subject. They are registered in standardized tests based on objective feelings and statements of each subject. In this paper two qualitative characteristics of Memic population are being analyzed: (in)ability to taste phenylthiocarbamide and (in)ability of rolling the lateral border of the tongue. There were 415 subjects of both sexes (207 male and 208 female) in Memic Primary school, Kalesija Municipality. It is determined that 217 subjects do not have the ability of sensing the bitter taste of phenylthiocarbamide, which is 52,29% of the whole sample group and the frequency of recessive allele in the whole sample is qt=0,72. With the analysis of alternative phenotypes frequency in the sample group of 415 subjects, 131 do not have the ability to roll the tongue, which is 31,57%. That makes the frequency of recessive allele in the whole sample qr=0,56. Testing t(%) frequencies of recessive allele in a gene qt and qr did not point to any significant difference between expected and observed frequencies in studied sample of male subjects, sub sample of female subjects, as well as within the whole sample group. With the analysis of age factor in recessive allele frequency qt i qr , a falling trend has been found in the male group, female group as well as in the whole sample group.
