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?
A) square root method
B) chi- square test
C) genotype proportion method
D) allele- counting method
E) binomial expansion

The allele-counting method is most helpful for identifying blood type allele frequency because it involves directly counting the alleles for each blood type in the population and then calculating their frequencies. This method is straightforward and effective for traits like blood type, where phenotypes directly correspond to genotypes due to codominance.
