In a sample of 2,400 people, 1,482 were found to have the dominant (taster) phenotype. Assuming that the population is in Hardy-Weinberg equilibrium, approximately how many individuals in the sample are expected to be heterozygous for TAS2R38?

Hardy Weinberg's principle states that in a population, genetic variation will remain constant from one generation to another if the disturbing factors are absent.

The number of individuals expected to be heterozygous for TAS2R38 is 1133.

Hardy-Weinberg Equation can be given as:

where,

p = dominant purebred frequency

2 pq = heterozygous frequency

q = recessive purebred frequency

The Hardy-Weinberg principle requires no mutation, no gene flow, random mating, population size, and no natural selection. The equation shows the genotype frequencies will be constant if the evolutionary mechanisms are absent.

Thus, the correct answer is 1133.
