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.
If, , and are the frequencies of the three genotypes at a locus with two alleles, then the frequency p of the A-allele and the frequency q of the B-allele in the population are obtained by counting alleles.he frequency (p) of an allele A is the fraction of the number of copies (i) of the A allele and the population or sample size (N), so.
