PTC Test Results Number of students in lab (population size): 23 Number of tasters: b 4376 tasters in a population (TT + T) Number of non-tasters: 7 %non-tasters in a population (tt) 0,0926 frequency of non-tasters in a population (tt) or q2 q2-2.4 q.eeY-frequency of the t allele p-q-1-o.bg5/ +qs1 frequency of the Tallele p's genotype TT-2, y geo y 8. It % of the class or 2pqs genotype Tt-2, yat or 12. % of the class 1. If a student in this class is known to be a taster, what is the chance that he or she is homozygous for the T allele (a 'supertaster')? %TT x100% = 0.52.96 2. Does this number match the number of students who were able to taste the PTC paper as soon as it touched their tongue (and they did not have to chew the PTC paper before they were able to taste it)?Explanation / Answer
3. Strictly going by the findings one can say that it is simple mandelian inheritance and is complete dominance as also the answer of question 2 is not available. But if we go by the findings and researchers it has been shown that ptc tasting has incomplete dominance which has three varieties of tasters, weak tasters and non tasters. Also evidence of multiple genes involved in inheritance pattern have also been shown.
