In the same population of patients you examined for sickle cell allele frequencies, you now want to test whether the disease symptoms are related to blood type. Since blood type is a codominant trait and the alleles are easily identifiable by the phenotype (blood type) of the individuals, which method is most helpful for identifying blood type allele frequency?
◦ allele-counting method
◦ genotype proportion method
◦ square root method
◦ binomial expansion
◦ chi-square test
