Comparison of Gene Ontology (GO) category (level 3) distribution between candidate genes and non-candidate gene. The red and blue bars represent candidate genes (Ka/Ks ratio >0.5) and non-candidate genes (Ka/Ks ratio <0.5) in each GO functional category, respectively. Candidate genes have higher percentage then non-candidate gene in seven categories, which are marked with asterisks. The sum of individual percentages exceeds 100% because most genes are classified in multiple categories.
