Fig. 4: Ks distributions between K. obovata and R. apiculata and K. obovata and V. vinifera and within K. obovata and R. apiculata.
From: Chromosome-scale assembly of the Kandelia obovata genome

Peaks of intraspecies Ks distributions indicate ancient whole-genome polyploidization events, and peaks of interspecies Ks distributions indicate speciation events
