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.
The letter q represents the frequency of the a allele. An example is, in a population of 100 organisms, if 45% of the alleles are A then the frequency is .45. The remaining alleles would be 55% or .55.This is the allele frequency. An equation called the Hardy Weinberg equation for the allele frequencies of a population is p2+ 2pq+ q2 = 1. P represents the A allele frequency.The letter q represents the a allele. Hardy and Weinberg also gave five conditions that would ensure the allele frequencies of a population would remain constant.60 individuals are homozygous dominant and 480 are heterozygous. 2. The allele for the ability to roll one s tongue is dominant over the allele for the lack of this ability. In a population of 500 individuals, 25 percent show the recessive phenotype.
