Distribution of the extent of discernible sequence homology between paralogs (in base pairs) downstream of the termination codon. Gene duplicates comprising the 12 linked sets were excluded in this analysis. (a) Cumulative data set comprising both ohnologs and non-ohnologs (n = 56 duplication events). (b) Data set partitioned into ohnologs (n = 46 duplication events) and non-ohnologs (n = 10 duplication events).
