The correct answer is:
C

Using the allele frequency equation:



Using the genotype frequency equation:

Frequency of heterozygotes
Frequency of heterozygotes

Frequency of heterozygotes
Frequency of heterozygotes
Calculate the Number of Heterozygotes in the Population
Number of heterozygotes = Frequency of heterozygotes × Total population size
Number of heterozygotes 500

Number of heterozygotes = 160
Therefore, the number of heterozygotes in a population of 500 is 160.
