GO annotations of a human gene a and a mouse gene b. GO terms in white ellipses are the currently available annotations of the gene, and the terms in the gray ellipses are the missing annotations. The human gene should be annotated with ‘GO:f’ and mouse gene missing annotations of ‘GO:e’ and ‘GO:g’. Annotations of these two genes are different but also complementary for each other
