One simple approach could simulate population divergence under realistic values of population-model parameters (including population size and divergence time) for different underlying values of the selection coefficient ([gamma]) and ask how weak purifying selection ([gamma] < 0) would need to be in order to generate a frequency distribution of [omega] values in which the confidence limits include the [omega] value for the observed data (and constitute a false inference of positive selection rather than purifying selection).
Estimation of selection coefficient from data on allele frequency in discrete generations.
Selection coefficients of 0 indicate equal fitness of recent and long-term colonists (i.
Such estimates, derived as ratios of standing genetic variance to the rate of mutational variance, are quite consistent with the results from laboratory mutation-accumulation experiments referred to above, as they imply average selection coefficients of heterozygous mutations of one to two percent.
If selection operates in opposing directions in two blocks, the resulting selection coefficient may be zero.
In particular, the components of fitness and the kin selection coefficient, r, depend only on phenotypic correlations.
The strong directional selection coefficients on habitat features typifying preferred sites brings up two related questions.
Letting u denote the probability of fixation, [Mu] the genomic mutation rate, and s the selection coefficient for mutant homozygotes, then the long-term effects of beneficial and deleterious mutations will be balanced when [[Mu].
The selection coefficient of the advantageous allele was generally small, ranging from 0.
The selection coefficient estimates do not rely upon distributional assumptions (Lande and Arnold 1983), but the standard parametric significance tests assume normality of residuals (Neter et al.
The dominance coefficients of the deleterious mutations are assumed to be negatively linearly dependent on the selection coefficient, h = [h.
0] must be inserted into equation (10) to yield the selection coefficient s.
The magnitude of the selection coefficient, S, for selection exerted on corolla flare by bumblebees at seed set was calculated from the slope of the regression line (Lande and Arnold 1983).
Table 1 shows the relationship between the mean extinction time, mutation rate, and selection coefficient.
