Abstract

Strains of Bacillus subtilis exchange linked blocks of genes when growing together in soil; such exchange leads to extensive reorganization of the genotypic structure of the population and to the appearance and eventual dominance of a single phenotype. This process illustrates how recombination and selection lead to adaptive changes in populations.
