From: Early evolutionary history and genomic features of gene duplicates in the human genome
Composition frequencies of three structural categories of DNA-mediated gene duplicates across three evolutionary age-cohorts. The sample sizes of duplicate pairs within each of the three categories (K S  = 0, 0 < K S  ≤ 0.025, and 0.025 < K S  ≤ 0.1) are provided above the corresponding bars (N = 163 gene duplicate pairs). There was a significant difference in the relative proportions of the three structural categories of gene duplicates (G = 11.9, p = 0.018) as a function of evolutionary age, K S
