Did you know that several factors can prevent the permanent fixation of an allele? These factors include gene flow, genetic drift, natural selection, and mutation. Gene flow occurs when individuals or their gametes migrate between populations, leading to the transfer of alleles. Genetic drift, on the other hand, is the random change in allele frequencies due to chance events. Natural selection acts to favor certain alleles over others based on their fitness, potentially preventing the fixation of less advantageous alleles. Lastly, mutations can introduce new alleles into a population, modifying the existing genetic composition and potentially preventing the fixation of a specific allele. Understanding these factors is crucial in studying how genetic diversity is maintained within populations.
