Occurrence ratios in comparative genomics. Maize, sorghum and rice whole genome shotgun reads were randomly selected to generate 0.45 × coverage with respect to each genome's size. The total number of 20-mers in each logarithmic frequency class (A) are contrasted to the number of different 20-mers in each frequency class (B). Maize is the most repetitive of the three grasses analyzed here, but a corresponding increase in genome complexity is not observed.
