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.
33. A student concluded that for Population 3, p is greater than q. Is this conclusion consistent with Table 2?
Your Answer is
Correct Answer is B
Explanation
Looking at table 2, the q of Population 3 is NP, which means that the data is not provided and we need to calculate it ourselves;
tt=0.04, so according to the tt formula given in table 1, we can know that q= 0.2, so choose B
