Factors that affect allele frequency
WebAllele frequency is different from genotype frequency or phenotype frequency. Genotype and phenotype frequencies can also be calculated and are important for understanding how populations evolve, but they are not the same thing as allele frequency.

Higher mutation rates can lead to greater genetic diversity and affect the pattern of heterozygosity. Natural selection: This is the process by which certain traits or alleles are favored or selected for, leading to changes in allele frequencies over time. shooting near berwyn il todayWebWhen a lot of mutations accumulate together over generations then this causes to change in the allele or genotype frequencies in a population. And when, other evolutionary forces like natural selection acts on those accumulated mutations evolution occurs respectively.
