Answer:
0.42
Explanation:
Since 70% of the gametes have an A1 allele, this means that the frequency of the A1 allele in the population is 70% or 0.7.
The population is in Hardy-Weinberg equilibrium. For this population, the frequency of another allele for the same locus (A2) would be= 1- frequency of A1 allele = 1-0.7 = 0.3
The proportion of flies carrying both A1 and A2 alleles would be = 2 x frequency of A1 allele x frequency of A2 allele.
So, frequency of heterozygous flies= 2 x 0.7 x 0.3 = 0.42 or 42%
