In genetics, anticipation is a phenomenon whereby as a genetic disorder is passed on to the next generation, the symptoms of the genetic disorder become apparent at an earlier age with each generation.In most cases, an increase of severity of symptoms is also noted.n order to have a deleterious effect, the number of repeats must cross a certain threshold. For example, normal individuals have between 5 and 30 CTG repeats within the 3' UTR of DMPK, the gene that is altered in myotonic dystrophy.
Gene flow is a process of evolution that takes place when genes or alleles move from one population to another. It is also known as the Gene Migration, and that could cause changes in the allele frequency as well as some variations in the gene pool of both populations.enetic Drift. Genetic drift is a mechanism of evolution of biological species that takes place because of the change in the frequency of alleles in a population. These changes in the allele frequency in a population occur randomly.
