Shifts in the intensity of purifying selection: an analysis of genome-wide polymorphism data from two closely related yeast species.

Genome research - 1 Nov 2010

Abstract excerpt

How much does the intensity of purifying selection vary among populations and species? How uniform are the shifts in selective pressures across the genome? To address these questions, we took advantage of a recent, whole-genome polymorphism data set from two closely related species of yeast, Saccharomyces cerevisiae and S. paradoxus, paying close attention to the population structure within these species. We...
