In a population of 1000 individuals, 360 belong to genotype AA, 480 to A a and the remaining 160 to aa . Based on this data, the frequency of allele A in the population is:

Solution & Step-by-step Explanation

Frequency of allele A (p): p^{2} = Frequency of AA = \frac{360}{1000} = 0.36 p = 0.36 = 0.6 Alternatively, calculating from total alleles:Total alleles = 1000 \times 2 = 2000 .Number of A alleles = (360 \times 2) + 480 = 720 + 480 = 1200 .Frequency of A = \frac{1200}{2000} = 0.6 .

Try it yourself before checking the explanation above.
