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.
(b) Now that you have q, you can solve for p. Remember there are only two alleles in the population, so if you add the frequency of the two alleles, you have accounted for all possibilities and it must equal 1.hink back to the Hardy-Weinberg equation -- it is dealing with the genotypes of individuals in the population. p2 + 2pq + q2 = 1. frequency of homozygous dominant + frequency of heterozygotes + frequency of homozygous recessive = 1. so.....2pq = frequency of heterozygotes.
