Distribution of minimum duplication spans (in kilobases) for S. cerevisiae gene-duplicate pairs with synonymous-site divergence of 0 ≤ K_S < 0.35. (a) Cumulative data set comprising both ohnologs and non-ohnologs (n = 68 duplication events). (b) Data set partitioned into ohnologs (n = 47 duplication events) and non-ohnologs (n = 21 duplication events).
