Burden of deleterious mutations during maize domestication and expansion. Comparison of counts of deleterious alleles at the individual level a between parviglumis and maize (mean value in parviglumis population was used as the standard to calculate the relative burden) and b among maize populations (mean value in Mexican lowland population was utilized as the standard to calculate the relative burden) under a recessive model. Comparison of fixed versus segregating (seg) deleterious alleles at the population level c between parviglumis and maize and d among maize populations. A jackknife sub-sampling approach (n = 4) was utilized for maize in c and for individual maize populations (n = 3) in d
