WebSep 9, 2010 · The breeder's equation, which predicts evolutionary change when a phenotypic covariance exists between a heritable trait and fitness, has provided a key conceptual framework for studies of adaptive microevolution in nature. However, its application requires strong assumptions to be made about the causation of fitness variation. WebThe breeder's equation as you wrote it: R = h 2 S. The heritability that is the ratio of additive genetic variance over the total phenotypic variance is called the heritability in the narrow …
WebEach plant in the trial receives a unique quantitative identifier, its plant prognostic equation value, according to the exclusive properties of the HSDs. The ensuing ranking is based on accurate and quantitative evaluation standards that exclude any visual selection and breeder’s bias during all stages of the breeding program. In selective breeding of plants and animals, the expected response to selection of a trait with known narrow-sense heritability can be estimated using the breeder's equation: In this equation, the Response to Selection (R) is defined as the realized average difference between the parent generation and the next generation, a…
WebThe Breeder’s Equation is a well-known expression in quantitative genetics that is widely used to understand how genetic gain can be achieved. Here, we will focus on a few statistical aspects of this equation and the role they play in helping us to maximize genetic gain. An expression of this equation is: x . where, WebMore generally, we can express the breeders equation as R = i r uA s A Where we select individuals based on the index u (for example, the mean of n of their sibs). r uA= the …

WebIn the breeder's equation, R = h 2 S. In animal and plant breeding, S is determined by the breeder. In natural selection, S is determined in part by the intensity of the struggle for existence in step 3 above, and by the adaptive landscape. The breeder's equation can be rewritten as .
