Selection determines the balance of horizontal versus vertical inheritance of plasmid-encoded HgR. Plasmid transfer in each of six replicate populations was tracked over time across the three mercury treatments (0, 20 and 40 μM HgCl2). Dotted lines indicate densities of recipient populations; solid lines indicate densities of donor populations. For each population, shaded regions represent plasmid prevalence within donor (purple) and recipient (blue) subpopulations.
