Understand that the problem is asking about the frequency of heterozygous individuals in a population, which is a concept from population genetics.
Recall the Hardy-Weinberg principle, which provides a mathematical model to study genetic variation in a population. The principle is expressed as: , where and are the frequencies of two alleles.
Identify the terms in the Hardy-Weinberg equation: represents the frequency of homozygous dominant individuals, represents the frequency of heterozygous individuals, and represents the frequency of homozygous recessive individuals.
Recognize that the term specifically represents the frequency of heterozygous individuals in the population.
Conclude that the correct term for the frequency of heterozygous individuals is .
