Fig. 3: Frequency of gene family size and the top 30 large clusters of orthologous genes.

a Frequency of gene families with a size greater than 100. b Frequency of gene families with a size less than 100. c The top 30 large clusters of orthologous genes. The number enclosed in parentheses is the number of orthologous gene groups annotated with the terms. Count: the number of genes related to the enriched GO term. GeneRatio: the ratio of genes related to the enriched GO term compared to the number of genes related to all GO terms in the cluster.
