Relatedness affects evolution of cheaters in D. discoideum

Description:

Summary[edit] Description: English: Kuzdzal-Fick et al. experimentally evolved replicate lines of D. discoideum under treatments enforcing low relatedness. Transfers were performed using 106 spores gathered from across the plate, effectively mixing the population each transfer. Cheater mutants were repeatedly exposed to new partners to exploit and so prospered. Obligate cheaters incapable of fruiting on their own readily evolved. Eventually, the pressure exerted by cheaters caused other genotypes to evolve ‘noble resistance’ – these strains could resist cheating without being cheaters themselves. Date: 31 May 2019.
