what is a genetic phenomenon
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.
