The strength of selection is measured by the selective effect, s, of a single gene and the strength of random genetic drift is indicated by (1/2Ne), where the population has effective size, Ne. When s exceeds (1/2Ne), then the evolutionary fate of a gene is determined primarily by Natural Selection.
