Analysis:
To determine the frequency of allele A in the population, we need to consider the genotypes of the individuals and their corresponding allele compositions. Let's break down the given data:
- Total population size: 1000 individuals
- Genotype AA: 360 individuals
- Genotype Aa: 480 individuals
- Genotype aa: 160 individuals
Calculating Allele Frequency:
To calculate the frequency of allele A, we can consider the following:
- Allele A is present in both the AA and Aa genotypes.
- Individuals with genotype AA have two copies of allele A.
- Individuals with genotype Aa have one copy of allele A.
We can calculate the frequency of allele A by summing up the number of copies of allele A and dividing it by the total number of alleles in the population.
- Number of copies of allele A in the population:
- From AA genotype: 2 copies x 360 individuals = 720 copies
- From Aa genotype: 1 copy x 480 individuals = 480 copies
- Total number of alleles in the population:
- Each individual has two alleles, so the total number of alleles is 2 x 1000 = 2000.
- Frequency of allele A:
- (720 + 480) / 2000 = 1200 / 2000 = 0.6
Conclusion:
Therefore, the frequency of allele A in the population is 0.6, which corresponds to option C.

- From Aa genotype: 1 copy x 480 individuals = 480 copies
- Total number of alleles in the population:
- Each individual has two alleles, so the total number of alleles is 2 x 1000 = 2000.
- Frequency of allele A:
- (720 + 480) / 2000 = 1200 / 2000 = 0.6
Conclusion:
Therefore, the frequency of allele A in the population is 0.6, which corresponds to option C.

The no. of individuals of genotype AA is 360.
We know that (A+a)^2 = 1 where A and a are the frequencies of both the alleles. Expanding, AA + 2Aa +aa= 1 where AA = A^2 ... and so on. This hypothetically means out of 1 individual, A^2 are of genotype AA. Means out of 1000 people 1000× A^2 are of genotype AA.
So, 1000×A^2 = 360 ; A^2= 0.36 so A =0.6 (ans. C)
