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.
where p is the frequency of the A allele and q is the frequency of the a allele in the population. 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.
1 The frequency of the recessive allele in the population. 2  Answer: We know from the above that q 2 is 1/2,500 or 0.0004. 3  Therefore, q is the square root, or 0.02. 4  That is the answer to our first question: the frequency of the cystic fibrosis (recessive) allele in the population is 0.02 (or 2%). 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%.
