Microevolution is the change in allele frequencies that occur over time within a population.igration into or out of a population can change allele frequencies, as well as introducing genetic variation into a population. Immigration may add new genetic material to the established gene pool of a population. Conversely, emigration may remove genetic material.
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.
