From: Early evolutionary history and genomic features of gene duplicates in the human genome
Composition frequencies of intra- and interchromosomal duplication within three age-cohorts of human gene duplicate pairs. The sample sizes of duplicate pairs within each age category (K S  = 0, 0 < K S  ≤ 0.025, and 0.025 < K S  ≤ 0.1) are provided above the corresponding bars. The total sample size comprised 172 duplicate pairs with assigned chromosomal locations for both paralogs. Chromosomal location is significantly associated with the K S values for paralogs (G = 25.1, p = 3.59 × 10−6)
