The consequences of genetic drift for bacterial genome complexity.

Genome research - 1 Aug 2009

Kuo Chih-Horng, Moran Nancy A, Ochman Howard

Abstract excerpt

Genetic drift, which is particularly effective within small populations, can shape the size and complexity of genomes by affecting the fixation of deleterious mutations. In Bacteria, assessing the contribution of genetic drift to genome evolution is problematic because the usual methods, based on intraspecific polymorphisms, can be thwarted by difficulties in delineating species' boundaries. The increased...
