Ответ:
Frequency of allele a2 is 25%, q=0.25
If a population is in Hardy-Weinberg equilibrium then:
p2+2pq+q2=1
p2 is the frequency of genotype a1a1 (homozygous),
2pq is the frequency of genotype a1a2 (heterozygous),
q2 is the frequency of genotype a2a2
The proportion of individuals with genotype a1a2 is then 2*0.75*0.25=0.375 (37.5%).
