 ## The GO hierarchy
 The GO is structured as a graph in which each GO term is a node and the relationships between the terms are relations, also known as *edges*, between the nodes. GO is hierarchical, with 'child' terms being more specialized than their 'parent' terms, but unlike a strict hierarchy, a term may have more than one parent term (note that the parent/child model does not hold true for all types of relations, see the [relations documentation](/docs/ontology-relations/)). For example, the biological process term [hexose biosynthetic process](http://amigo.geneontology.org/amigo/term/GO:0019319){:target="blank"} has two parents, [hexose metabolic process](http://amigo.geneontology.org/amigo/term/GO:0019318){:target="blank"} and [monosaccharide biosynthetic process](http://amigo.geneontology.org/amigo/term/GO:0046364){:target="blank"}. This reflect the fact that *biosynthetic process* is a subtype of *metabolic process* and a *hexose* is a subtype of *monosaccharide*.
