What would be a suitable term to call a binary relationship that is co-dependent yet not symmetrical to another relationship between the same entity in a binary relationship?  

If "John is a father of Chris”, how can we describe that relationship in terms of comparing it to “Chris is a son of John”?  Would “isomorphic”  be the best term to use? “Inverse”? Assume that the relationship is traversable from either side.

The context of this is in a graph database discussion group.  Graph Databases have nodes and relationships.  Either can have properties.  Unlike RDBMS systems, graph databases have relationships between instances of nodes, not a foreign key relationship with an entire table.

The binary relationship is not symmetric since true symmetry would require that the statements “..is a father of…” and “…is a son of…” be equally true for A-B as they are for B-A.

Sorry for this simple request.  I am just trying to find the best description for this.
