Calculation of Frequency of 'Aa' Genotype in the Next Generation
Given Information:
- Frequency of 'A' allele (p) = 0.7
- Frequency of 'a' allele (q) = 1 - p = 0.3
Hardy-Weinberg Equilibrium:
According to Hardy-Weinberg equilibrium, the frequencies of genotypes in a population remain constant from generation to generation if certain conditions are met.
Calculation:
- Using the Hardy-Weinberg equation: p^2 + 2pq + q^2 = 1
- Substituting the given values: (0.7)^2 + 2(0.7)(0.3) + (0.3)^2 = 1
- Calculating: 0.49 + 0.42 + 0.09 = 1
- Frequency of 'AA' genotype (p^2) = 0.49
- Frequency of 'Aa' genotype (2pq) = 0.42
- Frequency of 'aa' genotype (q^2) = 0.09
Therefore, the frequency of the 'Aa' genotype in the next generation is 0.42 according to Hardy-Weinberg's law.
