Percentage of intrafamily, interfamily, and randomly duplicated blocks. The total number of duplication events is the sum of all possible miRNA pairs within the set. Therefore, the percentage equals the total number of duplication events observed compared to the total number of possible duplication events. (A) Duplicated miRNAs from within the same family with the number of conserved protein-coding genes flanking the miRNAs. (B) Percentages of observed duplicated blocks against the total number of potential duplicated blocks and the number of flanking genes that are conserved within each block. (C) Plot comparing the percentage of observed duplication events against the total number of potential duplications for interfamily miRNAs, intrafamily miRNAs, and the randomized simulation.
