Understanding Hardy-Weinberg Equilibrium
The Hardy-Weinberg principle states that allele and genotype frequencies in a population will remain constant from generation to generation in the absence of evolutionary influences. For a gene with two alleles, 'A' and 'a', the allele frequencies can be denoted as follows:
- Frequency of allele A (p) = 0.7
- Frequency of allele a (q) = 1 - p = 1 - 0.7 = 0.3
Calculating Genotype Frequencies
To determine the expected genotype frequencies, we use the formula:
- Frequency of genotype AA = p²
- Frequency of genotype Aa = 2pq
- Frequency of genotype aa = q²
Now, let’s calculate each frequency:
- Frequency of genotype AA = (0.7)² = 0.49
- Frequency of genotype Aa = 2(0.7)(0.3) = 0.42
- Frequency of genotype aa = (0.3)² = 0.09
Finding the Frequency of Genotype 'aa'
Given that the genotype frequency of 'a' (which refers to 'aa') needs to be established:
- From our calculations, the frequency of genotype aa is q² = 0.09.
Conclusion
Among the options provided:
- (a) 0.21
- (b) 0.42
- (c) 0.36
- (d) 0.7
The correct answer for the frequency of genotype 'aa' is none of the options listed. The calculated frequency of genotype 'aa' is 0.09, which indicates that there might be an error in the provided options.
In summary, the population maintains its genetic structure in Hardy-Weinberg equilibrium, allowing us to derive allele and genotype frequencies accurately.
