Study Notes
Hardy-Weinberg Equilibrium Equation
- The equation is: $p^2 + 2pq + q^2 = 1$
- 'p' represents the frequency of the dominant allele
- 'q' represents the frequency of the recessive allele
Frequency of Alleles and Genotypes
- If the frequency of the recessive allele (q) is 0.0071, the frequency of the dominant allele (p) is $\sqrt{1 - 0.0071^2}$
- In a population with complete dominance, if the frequency of the recessive allele (q) is 0.0071, the heterozygous genotype frequency is $2pq = 2 \times p \times 0.0071$
- If the frequencies of dominant genotypes (D) and heterozygous genotypes (H) are 26 and 12 respectively, the value of 'p' can be calculated using the equation: $D = p^2$, where $p^2 = 26$
H^2 Equation
- The equation is: $H^2 = 4DR$
- If $D = 0.04$ and $R = 0.64$, the value of $H^2$ is $4 \times 0.04 \times 0.64 = 0.1024$
Q Equation
- The equation is: $Q = \frac{χ^2}{N}$
- If χ² = 0.32 and N = 40, the value of Q is $\frac{0.32}{40} = 0.008$
