Fig. 8From: GO functional similarity clustering depends on similarity measure, clustering method, and annotation completenessFrequency distribution of missing annotations among human genes. The x-axis represents the number of missing annotations of each human gene compared with its “well-annotated” ortholog in yeast (cellular processes) or mouse (multicellular organism processes). The degree of incompleteness of human gene annotation is much greater for multicellular processes than cellular processesBack to article page
