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.
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.
