By contrast, for the humans, it is known that the B2 kids are the parents of the B1 kids. However, as the term appears to mostly deal with the "perceived" direction of the relationships, it could be seen as applicable to the humans as well; as few of them are aware that their grandparents/ancestors are their children.
