# Among the 1000 people, 360 people belong to genotype AA, 480 people to Aa, and the remaining 160 people to aa. Based on this data, the frequency of allele A in the community is:A. 0.4B. 0.5C. 0.6D. 0.7

Hint: The proportion of an allele's overall repetition on a genetic locus in a population is known to be Allele frequency. In general, it is communicated to an extent or a rate. The allele frequencies show the hereditary variety of an animal group's population or proportionally the lavishness of its genetic stock, in the community hereditary qualities.

The total number of people = 1000
Genotype recurrence of AA = $\dfrac{360}{1000}$ = 0.36
Genotype recurrence of aa = $\dfrac{160}{1000}$ = 0.16
Genotype recurrence of Aa = 2x $\dfrac{240}{1000}$ = 0.48
Presently, as per the Hardy Weinberg balance,
The square of the whole of allele frequencies gives the individual genotype frequencies in a non-developing stable populace.
(A+a)x2= AA + 2Aa +aa
Consequently, allele recurrence of A = $\sqrt{0.36}$ = 0.6
Allele recurrence of a = $\sqrt{0.16}$ = 0.4
Hence, Option (c) 0.6 is the correct answer.
