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:
                             
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 yet another population. You observe that the AB blood type has a frequency of 0.50 in this population. What are the frequencies of the A and O alleles in this population?

#Unit 8. Inheritance Biology
  1. Frequency of the A allele = p = 0.5      
    Frequency of the O allele = r = 0
  2. Frequency of the A allele = p = 0.5      
    Frequency of the O allele = r = 0
  3. Frequency of the A allele = p = 0.5      
    Frequency of the O allele = r = 0
  4. Frequency of the A allele = p = 0.5      
    Frequency of the O allele = r = 0
