Phenotypic heterogeneity meaning
WebMay 1, 2024 · Phenotypic plasticity is defined as the property of organisms to produce distinct phenotypes in response to environmental variation. While for more than a century, biologists have proposed this organismal feature to play an important role in evolution and the origin of novelty, the idea has remained contentious. WebPhenotypic heterogeneity can have important functional consequences, it can provide individuals and groups with new functionality, and it can also enable survival in stressful conditions such as lack of oxygen and nutrients or antibiotic influence.

Phenotypic heterogeneity meaning
Did you know?
Genetic heterogeneity occurs through the production of single or similar phenotypes through different genetic mechanisms. There are two types of genetic heterogeneity: allelic heterogeneity, which occurs when a similar phenotype is produced by different alleles within the same gene; and locus heterogeneity, which occurs when a similar phenotype is produced by mutations at different loci. WebDec 23, 2024 · Most phenotypic traits vary among individuals within a genetically identical population. The level of such phenotypic heterogeneity is crucial to biological evolution. On the one hand, low heterogeneity may increase the efficacy of natural selection via better phenotypic separation between populations of different genotypes (Wu et al. 2009).
