Gene conversion rescues oligoploid populations, but can be detrimental if ploidy level is high and conversion is not frequent enough to ensure homozygosity. a In diploid population, even infrequent gene conversion is beneficial. 2-ploid_conversion01: R conv  = 0.1, each gene undergoes conversion with average probability 0.011 per generation, which is comparable with mutation rate (M = 0.007); 2-ploid_conversion1: R conv  = 1, probability of conversion is 0.11 per gene, which is 1 order of magnitude higher than the mutation rate; the population is rescued. b In 6-ploid population, conversion rates R conv  = 0.1 and 1 are detrimental, and only at R conv  = 4 (conversion probability 0.44, which is 63 times higher than the mutation rate) the population is rescued. c In 18-ploid population, even R conv  = 8 (conversion rate 0.88) is not enough to rescue the population
