Gene flow
Seed-mediated gene flow promotes genetic diversity of weedy rice within populations: implications for weed management.
... Our results from UPGMA cluster and Mantel test suggested little association between genetic relatedness and spatial location of weedy rice populations. In other words, weedy rice populations with close spatial locations ...

Altruism can proliferate through population viscosity despite high random gene flow.
... In contrast, we show that for iterated public goods games, in which altruists cooperate or not in each round based on previous outcomes [35,36], altruism can spread even when cost/benefit ratios for each altruistic act ...
