cis versus trans effects

Pennisi E 2008 Deciphering the genetics of evolution. Science 321:760-763. early suggestions that gene regulation could be important to evolution came in the 1970s from work by bacterial geneticists showing a link between gene expression a…

fixation probability

Patwa Z & Wahl LM 2008 The fixation probability of beneficial mutations. J R Soc Interface 5:1279-1289. Lambert pointed out that the factor 2 in Haldane's result of π ≈ 2s for very small s stems from the assumption that the offspring distr…
