Syntenic dotplot between Brassica rapa and Arabidopsis thaliana. Syntenic gene-pairs are colored by Ks values. Dark red: orthologs; pink: from shared most recent whole genome duplication event; purple: from shared second most recent whole genome duplication event. Brassica's triploidy is seen by having each region of Arabidopsis thaliana having three dark red regions in B. rapa, while a single region of B. rapa has one dark red region in A. thaliana. Results can be regenerated at http://genomevolution.org/r/nty .Histogram of Ks values between Brassica rapa and Arabidopsis thaliana. Ks values are log transformed, low values on left (little change); high values on right (more change). Peaks correspond to genome duplication events. Colors in this histogram match colors in the syntenic dotplot. Results may be regenerated at http://genomevolution.org/r/nty .
