In genetic drift process, rapid change in gene variation is readily noticeable in small reproductive isolated population. (Zimmer & Emlen, 2013). Smaller population is more affected by genetic drift due to less allele to balance out the effect of random changes. Small population also increases the likelihood of inbreeding that negatively affects the changes in allele frequencies over time, allowing recessive genes to be dominant over a small population hence causing the rapid genetic variation. For example, from the above experiment there is an explicit indication of abnormal frequency outcome from two flip coin results compared to a fifty flip coin results.
Factors affecting Allele frequencies: various factors can cause the dominance of allele in a given population. These factors include genetic isolation that refers to the separation of potentially interbreeding animals. This condition reduces the chances of balancing allele frequency by facilitating the development of a less dominant allele into the future generation. Selective sexual selection affects the allele frequency where only particular phenotypes get selected by mates. The allele of the chosen ones increases in the frequency and those not chosen will decrease. For example in peacock, fancy feathers males are chosen to reproduce. Another factor is genetic drift that occurs in small populations. Chance, mating, or luck can dramatically change the frequency of alleles in the small gene pool.
Buri experiment: He set up over 100 replicate populations of 16 Drosophilla flies and follows each population for many generations to measure variation in allele frequency. All of the population used in the experiment begun with 8 males and 8 females that were all heterozygous for an eye color mutation. Drosophila eye coloration for genotype was easily observed. He took 3 different genotypes which ...Download file to see next pagesRead More
