Expressivity definition of expressivity by Medical dictionary

WebVariable expressivity refers to the range of signs and symptoms that can occur in different people with the same genetic condition. As with reduced penetrance, variable expressivity is probably caused by a combination of genetic, environmental, and lifestyle factors, most of which have not been identified.

WebMar 15, 2024 · Studies on the reproductive dynamics under heat stress are crucial to breed more tolerant cultivars. In tomato, cultivars, breeding lines, and wild species have been evaluated for their response to heat stress. Here, we addressed the study to a panel of selected landraces representing traditional genotypes that usually show high adaptation … WebThe frequency, expressed as a fraction or percentage, of people who are phenotypically affected, among people of an appropriate genotype; factors affecting expression may be environmental, or due to purely random variation; contrasted with hypostasis where the condition has a genetic origin and therefore tends to cause correlation in relatives. WebPenetrance and expressivity are related to a) the expression of one gene masking the effects of another gene. b) quantitative traits that diminish or intensify a particular phenotype. c) the influence of environment on the expression of a particular genotype. d) the increased expression of a particular trait when a hybrid species is formed. bloodhound\u0027s step
