Joint distributions of allelic frequencies in O. sativa groups. (a) AFS of 965,497 indica + japonica alleles absent in the progenitor population of japonica. (b) AFS of 612,951 indica + japonica alleles absent in the progenitor population of indica. (c) AFS of 261,775 indica + japonica alleles absent in O. rufipogon. (d) AFS of 233,812 indica + aus alleles absent in the progenitor population of indica. (e) AFS of 323,665 indica + aus alleles absent in the progenitor population of aus. (f) AFS of 162,523 indica + aus alleles absent in O. rufipogon. (g) AFS of 303,652 japonica + aus alleles absent in the progenitor population of japonica. (h) AFS of 276,813 japonica + aus alleles absent in the progenitor population of aus. (i) AFS of 142,381 japonica + aus alleles absent in O. rufipogon. Axes show allelic frequency classes in respective groups. Proportions of alleles at any combination of frequency classes are indicated with logarithmic-scale shading, and also as percentages under delineated areas
