Abstract. The genetic response to selection is central to both evolutionary biology and animal and plant breeding. While Price's theorem (PT) is well-known in evolutionary biology, most breeders are unaware of it.
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.
For example, the Price equation in its most abstract form does not contain enough information to follow evolutionary dynamics through multiple rounds of natural selection. By contrast, classical dynamic models of population genetics are sufficient to follow change through time.
11 mar 2008 · The Price equation describes the change in the average value of the character between the two generations. This is given by Δ z ¯ i = z ¯ ′ i − z ¯ i, where z ¯ ′ i and z ¯ i are the averages in the offspring and parent generations, respectively.
4 kwi 2020 · The Price equation is widely recognized as capturing conceptually important properties of natural selection, and is often used to derive versions of Fisher’s fundamental theorem of natural selection, the secondary theorems of natural selection and other significant results.
5 sie 2021 · These examples show how the logic and language of the Price equation can be used in several areas of evolutionary biology through the derivation of new forms of the Price equation. As this is not an algorithmic process, different researchers may develop different forms of the Price equation in a particular scientific area, depending on their ...
