Q. In a population of 1000 individuals 360 belong to genotype AA, 480 to Aa and the remaining 160 to aa. Based on this data, the frequency of allele a in the population is :
A) 0.4
B) 0.5
C) 0.6
D) 0.7
Explanation
[Solution] Number of a alleles = 480 + 2 × 160 = 800 out of 2000, so q = 0.4. (The key in the PDF gives (3) 0.6, which is the frequency of A.) Answer (1).
