The act was introduced as part of Canada's process of patriating the constitution, introducing several amendments to the British North America Act, 1867, and changing the latter's name in Canada to the Constitution Act, 1867.
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.
Genetic Drift Defined. Populations of organisms are constantly changing and adapting to their environment. Drastic changes in environmental conditions can sometimes cause drastic changes to the gene pool of the population. Genetic drift is when chance events cause changes in frequencies of alleles in a population. Alleles are the genetic variations in a population, and they are the driving force behind the evolution of that population. The smaller the population, the greater the impact genetic drift will have.
