Consider the ABO “blood type” gene. This single gene has three alleles called A, B, and O. There are four resultant “blood types” (phenotypic classes), as follows: C
Assume Hardy-Weinberg equilibrium, the frequencies of the A and B alleles are 0.26 and 0.07, respectively. You now examine the ABO blood types in a new population. You observe that the A, B, and O blood types all have equal frequencies in this population. What are the frequencies of the A and O alleles in this population?
