9 mar 2020 · The equation then yields an exact mathematical description of the evolutionary change between the parent and offspring populations, that holds true quite generally, and it expresses that change as the sum of two components which have natural biological interpretations.
9 mar 2020 · The Price equation has found widespread use in many different areas of evolutionary biology. Here, we have illustrated how it can also provide useful insight into the evolutionary biology of infectious diseases.
11 mar 2008 · The Price equation separates the total change into two component parts. The first part is the change that can be ascribed to the action of selection, and this takes the form of a statistical covariance between individuals’ character values (z) and their relative reproductive success (w / w ¯).
9 mar 2020 · The Price equation, therefore, measures the effect of natural selection on every gene frequency, and on the breeding value of any trait, while the fundamental theorem measures natural selection in its totality as the additive genetic variance in relative fitness.
The Price equation is a mathematical relationship between various statistical descriptors of population dynamics, rather than a physical or biological law, and as such is not subject to experimental verification.
27 cze 2019 · Here we offer a conceptual framework to study the evolutionary origins and ecological circumstances of species in beneficial symbiosis. We posit that mutual symbiotic interactions are well described by three elements: a currency, the mechanism of currency exchange, and mechanisms of symbiont inheritance.
Definition. Mathematically derived formula of evolutionary change (Price 1970). Due to population geneticist George Price in 1970, this equation expresses the between-generation change in a trait mean value in the following way :
