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.
When there are two alleles at a locus, the convention is to use p to represent the frequency of one allele and q to represent the frequency of the other. Thus p, the frequency of the CR allele in this population, is 0.8. The frequency of the CW allele, represented by q, is 0.2.
