Huntington's disease genotype and phenotype
WebFor example, phenotypic expression of a particular phenotype may be modified by age, termed age-related penetrance. Sometimes, as age increases, penetrance increases. For example, only 25% of individuals with a specific Huntington disease genotype (41 repeats) exhibit symptoms at age 50, while 75% exhibit symptoms at age 65. WebThe genotype of an organism is the genetic code in its cells. This genetic constitution of an individual influences – but is not solely responsible for – many of its traits. The phenotype is the visible or expressed trait, such …
