Distribution of genes (2A) and phenotypes (2B) based on their number of distinct associations. Each ontology term is considered a distinct phenotype regardless of its position in the ontology tree. Therefore, a gene will be counted as associated with two distinct phenotypes if different lines of evidence link it to a child term and its parent term.
