Problem

In humans, the ability to taste the chemical phenylthiocarbamide (PTC) is primarily controlled by a single gene that encodes a bitter taste receptor on the tongue. Tasters, or individuals that can taste PTC, have at least one copy of the dominant allele (T). Non-tasters, or individuals who cannot taste PTC, have two copies of the recessive allele (t).
The numbers of tasters and non-tasters in two separate human populations are shown in the table below.
Population 1
PhenotypeNumber of individuals
Tasters1848
Non-tasters352
Total2200
Population 2
PhenotypeNumber of individuals
Tasters1224
Non-tasters576
Total1800
If the two populations are each in Hardy-Weinberg equilibrium, which of the following graphs shows the correct genotype frequencies for the populations?
