In a study of genetic variation at the Bruin gene (thought to
determine school spirit), a researcher finds two alleles in a
population of 1000 UCLA students. It is determined that the
frequency of heterozygotes in the population is 0.63. Which of the
following best explains why the population is not in Hardy-Weinberg
equilibrium?
D. There would be no heterozygotes if the population were in
Hardy-Weinberg equilibrium.
A. The frequency of each genotype would be equal if the
population were in Hardy-Weinberg equilibrium.
C. The highest possible frequency of heterozygotes under
Hardy-Weinberg equilibrium is 0.5.
B. The frequency of heterozygotes would be 1 if the population
were in Hardy-Weinberg equilibrium.
