The аbility fоr humаns tо tаste the chemical PTC is cоntrolled by a single gene that codes for a bitter-taste receptor on the tongue. Tasters have at least one dominate allele. These individuals would experience a bitter taste when PTC is put on the tongue. Non-tasters have two recessive alleles and PTC would be tasteless to these individuals. Using the Hardy-Weinberg Equilibrium equation: If 64 individuals out of a population of 100 are non-tasters, determine q2, q, p2, p, 2pq. Round to two decimal places.
