What is phenotypic plasticity quizlet?
What is phenotypic plasticity? The ability of a genotype to produce distinct phenotypes when exposed to different environments throughout its ontogeny.
What is phenotypic plasticity examples?
Phenotypic plasticity refers to the ability of a genotype to express different phenotypes depending on the environment in which it resides. For example, genetically identical water flea (Daphnia) clones can differ in their morphology depending on whether reared in the absence or presence of a potential predator.
What is the best definition of phenotypic plasticity?
Phenotypic plasticity can be defined as ‘the ability of individual genotypes to produce different phenotypes when exposed to different environmental conditions’ (Pigliucci et al. As with any organismal trait, the way in which an individual responds to environmental influences is subject to evolutionary change.
What is phenotypic plasticity in humans?
Phenotypic plasticity refers to the ability of individuals with a given genotype to show variation in phenotypes under different conditions (e.g., Kelly, Panhuis, & Stoehr, 2012; From: Advances in the Study of Behavior, 2019.
What is phenotypic plasticity and why is it important?
Many organisms have the ability to express different phenotypes in response to environmental conditions. Such phenotypic plasticity allows individual organisms to develop appropriate morphological, physiological, or behavioral traits that better fit a particular environment that they encounter.
Why is plasticity important for development quizlet?
Why is plasticity important for development? Because plasticity speeds up development. Because plasticity ensures that change happens at a rate that the individual can manage. Because without plasticity, it would be impossible to remember things.
How does phenotypic plasticity occur?
Phenotypic plasticity is the ability of one genotype to produce more than one phenotype when exposed to different environments. Horizontal lines show that the phenotype is the same in different environments; slanted lines show that there are different phenotypes in different environments, and thus indicate plasticity.
How does phenotypic plasticity relate to evolution?
If the optimal phenotype in a given environment changes with environmental conditions, then the ability of individuals to express different traits should be advantageous and thus selected for. Hence, phenotypic plasticity can evolve if Darwinian fitness is increased by changing phenotype.
What is phenotypic plasticity biology?
Phenotypic plasticity can be broadly defined as the ability of one genotype to produce more than one phenotype when exposed to different environments, as the modification of developmental events by the environment, or as the ability of an individual organism to alter its phenotype in response to changes in …
Why does phenotypic plasticity occur?
Phenotypic plasticity describes the process that allows individuals to alter their phenotype in response to environmental change alter their phenotype due to new environments. This change in gene expression allows for phenotypic plasticity, as changes in mRNA expression have a direct link to protein abundance.
What is the significance of plasticity quizlet?
the ability of an experience to influence neural activity in such a way that it alters neural circuitry and thus determines behavior. maximal during critical periods.
