Organic acids are ubiquitous throughout the field of chemistry. Whether used as a solvent, a substrate, a strong acid, or in a catalytic amount as a Bronsted acid source, organic acids are as commonplace as glassware for the researcher.
In the equation, p 2 represents the frequency of the homozygous genotype AA, q 2 represents the frequency of the homozygous genotype aa, and 2pq represents the frequency of the heterozygous genotype Aa. In addition, the sum of the allele frequencies for all the alleles at the locus must be 1, so p + q = 1.
1 Answer: Since we believe that the homozygous recessive for this gene (q 2) represents 4% (i.e. = 0.04), the square root (q) is 0.2 (20%). 2  The frequency of the dominant allele. 3  Answer: Since q = 0.2, and p + q = 1, then p = 0.8 (80%). Since q equals the frequency of the a allele, then the frequency is 60%. 2  The frequency of the A allele. 3  Answer: Since q = 0.6, and p + q = 1, then p = 0.4; the frequency of A is by definition equal to p, so the answer is 40%.
