Evolution of mean viability under NM or EFC through 50 generations after a reduction of population size to N = 10. Ancestral population at the MS balance for one locus with s = 0.4, h = 0, μ=0.001. Upper plate: results when the population is maintained under EFC while N = 10. Remaining plates: EFC results (thick line) vs. NM results (thin lines). Red: simulation results; green: neutral predictions computed ignoring new mutation; light blue: IP predictions; deep blue: FM predictions.
