Consider a sample of 100 individuals sampled from a population in Hardy-Weinberg equilibrium that are genotyped at a single locus. Of these 100 individuals, 25 individuals are A1A1, 45 are A1A2, and 30 are A2A2. What is the actual (observed) allele frequency of the A1 allele in this sample? (you may use a calculator if needed) O A. 0.325 O B. 0.275 O C. 0.475 O D.0.525
