The influence of GC-biased gene conversion on non-adaptive sequence evolution in short introns of Drosophila melanogaster.

Abstract excerpt

Population genetic inference of selection on the nucleotide sequence level often proceeds by comparison to a reference sequence evolving only under mutation and population demography. Among the few candidates for such a reference sequence is the 5' part of short introns (5SI) in Drosophila. In addition to mutation and population demography, however, there is evidence for a weak force favouring GC bases, likely...
