Data from: Genetic drift and selection in many-allele range expansions

Bryan T. Weinstein, Maxim O. Lavrentovich, Wolfram Moebius, Andrew W. Murray, David R. Nelson & Wolfram Möbius
We experimentally and numerically investigate the evolutionary dynamics of four competing strains of E. coli with differing expansion velocities in radially expanding colonies. We compare experimental measurements of the average fraction, correlation functions between strains, and the relative rates of genetic domain wall annihilations and coalescences to simulations modeling the population as a one-dimensional ring of annihilating and coalescing random walkers with deterministic biases due to selection. The simulations reveal that the evolutionary dynamics can...
