WebJul 25, 2024 · The same genetic variant found in different individuals can cause a range of diverse phenotypes, from no discernible clinical phenotype to severe disease, even among related individuals. Such variants can be said to display incomplete penetrance, a binary phenomenon where the genotype either causes the expected clinical phenotype or it does … WebGenetic background and environment contribute to incomplete penetrance, in which not all individuals with a genotype display a corresponding phenotype, and variable expressivity, in which individuals of a particular genotype may have stronger or weaker versions of a phenotype.

WebThe differences of penetrance and expressivity occur because males and females have different sex hormones and because of other factors. For example, premature baldness (known as male-pattern baldness) is a non–X-linked dominant trait, but such baldness is rarely expressed in females and then usually only after menopause.
