Fig. 6From: Genome-wide analysis on the maize genome reveals weak selection on synonymous mutationsRelative contribution of each feature to the allele frequency spectrum of synonymous mutations. a Scatterplot showing the relationship between DAF/MAF and the change of CAI/tAI values. Each dot represents a synonymous mutation. Colors representing different sets of sites are explained next to the plot. b Regression coefficients of CAI, tAI and GC content against DAF/MAFBack to article page
