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.
The founder effect is a special case of genetic drift, occurring when a small group in a population splinters off from the original population and forms a new one.s a result of the loss of genetic variation, the new population may be distinctively different, both genotypically and phenotypically, from the parent population from which it is derived. In extreme cases, the founder effect is thought to lead to the speciation and subsequent evolution of new species.
