Which of the following formulas can be used to calculate heterozygote frequency in a population?
A
p2
B
q2
C
2pq
D
p-q

1
Understand the context: The problem is about calculating heterozygote frequency in a population using the Hardy-Weinberg principle.
Recall the Hardy-Weinberg equation: The equation is p^2 + 2pq + q^2 = 1, where p and q represent the frequencies of two alleles in a population.
Identify the terms: In the equation, p^2 represents the frequency of the homozygous dominant genotype, q^2 represents the frequency of the homozygous recessive genotype, and 2pq represents the frequency of the heterozygous genotype.
Focus on heterozygote frequency: The term 2pq in the Hardy-Weinberg equation specifically calculates the frequency of heterozygotes in the population.
Conclude with the correct formula: Therefore, the formula 2pq is used to calculate the heterozygote frequency in a population.

Put all the candies used in Problems 41 back into a single mound and then divide them into two piles, being sure that the frequencies of each color are the same in each pile. Make a note of the starting frequency of each color. Label one pile 'male' and the other pile 'female.'Have one person blindly draw one candy from the male pile and one candy from the female pile. Record the colors as though they were genotypes.
