Allele Frequencies
p (A allele):0.3000
q (a allele):0.7000
Note: p + q = 1 (Hardy-Weinberg equilibrium)
Expected Genotypes (H-W)
AA (p²):9.0
Aa (2pq):42.0
aa (q²):49.0
What is Allele Frequency?
Allele frequency refers to how often a particular allele appears in a population. According to the Hardy-Weinberg equilibrium principle, allele frequencies remain constant from generation to generation in the absence of disturbing factors. The equation p + q = 1 represents the frequency of the two alleles, where p is the dominant allele and q is the recessive allele.
