Passage VI
Tasters are people who can taste Chemical P. Nontasters are people who cannot taste Chemical P. The ability to taste Chemical P is determined by Gene T, which has 2 alleles: T and t. In a population that is not evolving—a population in Hardy-Weinberg equilibrium (HWE)—the frequency of allele T is p and the frequency of allele t is q. Table 1 shows the Gene T genotype(s) of tasters and of nontasters and the expression that predicts the frequency of each genotype in a population in HWE. Table 2 shows p, q, and the frequency of each Gene T genotype for 4 populations in HWE.
31. Based on Table 2, in which population would the number of people with the genotype TT and the number of people with the genotype tt be closest to the same?
Your Answer is
Correct Answer is A
Explanation
As can be seen from table 2, the TT frequency in Population 1 is equal to the tt frequency
