Removing parent object behaviour

I have one parent object and multiple child objects that inherit from the parent object. What happens in the database when I delete the parent object? Does this automatically delete the child objects that inherit from this parent, or do I have to loop through the parent objects, cast them and then delete the child objects? I'm currently using version 2.5.3 of the modeler. Thanks!

When deleting the parent the children that have a generalisation of the parent are deleted as well.
