In the basicfamily example, a person can have a father and a mother. Both properties are derived. In addition, there are also parents and children properties. What I do not understand is the following scenario:
There is a person named John. Alex and Joanne are the parents of John. When using a model editor, why is Alex set as the father of John and Joanne as the mother. There is nothing in the ecore file defining this relationship.

You're right that there is nothing in the Ecore itself.
It's defined directly in the Java implementation through custom "@generated NOT" versions of "getMother", "setMother", "getFather" and "setFather".
You can see the code here: https://github.com/pcdavid/org.eclipse.sirius/blob/master/plugins/org.eclipse.sirius.samples.family/samples/org.eclipse.sirius.sample.basicfamily/src/org/eclipse/sirius/sample/basicfamily/impl/PersonImpl.java#L187
