A) 0.375
B) 0.5625

The Hardy-Weinberg principle can be used to calculate the frequencies of genotypes in a population if the allele frequencies are known. The frequency of A1A2 individuals can be calculated using the formula 2pq, where p is the frequency of one allele (A1 = 0.75) and q is the frequency of the other allele (A2 = 0.25). Thus, 2 * 0.75 * 0.25 = 0.375.
