genetic drift

Genetic drift is one of the major mechanism of evolutionary change and has significant implications for human interactions. Different form of the same gene are known as alleles. A population is all the individuals of a species living in a particular place at a particular time. the relative proportion of an allele in a population is the allele frequently. The sum of all genes in a population is the gene pool. Hardly weinberg equilibrium is the maintained of a population is not evolving. The alleles responsible for blue color has ben lost, such loss of alleles is usually consequence of genetic bottleneck. Population bottleneck can cause all of the following except: changes in allele frequency. Loss of alleles. Reduction in genetic variability. Bottleneck happens to small population. The effects on evolution change are random. There is a loss of genetic variation after a bottleneck in our example. The allele for blue coloration was lost.
