You're interested in the genetics of earlobe shape on your campus. Free (unattached)earlobes are caused by a dominant allele. The attached earlobe phenotype is caused by a recessive allele. Individuals with free earlobes have either a homozygous genotype or a heterozygous genotype. Assuming that your college campus is a stable population, how could you use one calculation to determine the percentage of students who have a heterozygous genotype for earlobe shape?

Question

The percentage of people with attached earlobes (recessive phenotype) can be used to determine the frequency of the recessive allele, which can then be used to calculate the percentage of heterozygous individuals using the Hardy-Weinberg principle.
