Selection response refers to how much average change we expect for an offspring generation. To calculate the selection response (R), multiply the selection differential (S) by the trait’s heritability (h^2). Formula: R = h^2 x S. This value is important because it predicts potential improvement in subsequent generations, which may fulfill ... Differential fitness. Differential fitness is the third of Darwin 's four postulates for natural selection. It states that survival and reproduction rates vary between individuals. Fitness differentials are widespread and detectable throughout nature. This fitness differential is visible in several ways, and it can be detected throughout nature. Further, it is not possible to find a EC-based filter cost-sensitive feature selection method in the literature, to the best of our knowledge. We therefore design a cost-sensitive evaluation criterion using the principles of fuzzy mutual estimator and then adopt the criterion in differential evolution framework.All equations of response to selection were presented, using the selection differential for trait units (ds). This can be substituted by the standardized ...Footprints of local selection within each species were first detected using FDIST2 (Beaumont & Balding, 2004), which assumes that loci under putative diversifying selection would show elevated population differential condition on their heterozygosity.

In plant breeding, heritability is often calculated (i) as a measure of precision of trials and/or (ii) to compute the response to selection. It is usually estimated on an entry-mean basis, since the phenotype is usually an aggregated value, as genotypes are replicated in trials, which stands in contrast with animal breeding and human genetics.The selection differential, s, is the difference in mean of the selected parents versus to unselected parents (red vs red+blue distributions on the horizontal axis).
