From: Adaptive evolution driving the young duplications in six Rosaceae species
The Ka/Ks ratios of young duplicate genes in the two types of expansions. The box plots are exhibiting the distributions of Ka/Ks values among paralogs and orthologs in the two expansion types. The small square and the line in the box represent average and median values of the Ka/Ks values, respectively. a: F. vesca, b: M. x domestica, c: P. communis, d: P. persica, e: R. chinensis and f: R. occidentalis
