In a study of genetic variation of the graceland gene, a researcher finds that there are two alleles in a population. in a large sample (500 individuals), the frequency of heterozygotes is 0.63. is the population in hardy-weinberg equilibrium? 1. no. the highest frequency of heterozygotes under hardy-weinberg equilibrium is 0.5.2. no. the frequency of each genotype would be equal if the population were in hardy-weinberg equilibrium.3. no. the frequency of heterozygotes would be 1 if the population was in hardy-weinberg equilibrium. no. there would be no heterozygotes if the population were in hardy-weinberg equilibrium.
