Estimates of selection parameters in Drosophila.

We note that these estimates are not really comparable, as they are derived under different assumptions, not to mention different species and modes of inheritance.In the column titled s is the reported estimate of the strength of selection, under ν the reported estimate of the rate of adaptive substitutions per base pair per generation and under νγ = 2Nesνis the reported compound estimate (see text).aTwo populations are used for inference, resulting in two separate estimates of the parameters.bThe parameters were estimated from the mode of the posterior distribution sample, assuming specific distributions for the selection coefficient and rates of adaptation.
