Population genetics studies how mutant forms of genes spread in space and can eventually take over a population. The physical mechanisms underlying this process can be very different in the ocean, where flows can radically alter the chances of genes being fixated. I will present a new model that generalizes basic models of population genetics in the presence of a fluid flow. I will show that even the presence of a weak compressible flow has a dramatic effect on the fixation times and probabilities. I will then discuss the possible consequences of these findings for understanding the behavior of plankton populations in the oceans.
