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 The allele frequencies of each allele. 2  Answer: Well, before you start, note that the allelic frequencies are p and q, and be sure to note that we don't have nice round numbers and the total number of individuals counted is 396 + 557 = 953. 3  So, the recessive individuals are all red (q2) and 396/953 = 0.416.
