Which family bond is strongest?

Like father/son, mother/son, father/daughter, daughter/brother, etc. Maybe even niece/aunt, nephew/uncle, etc.

For some reason I always get mother/son seemed to be the "strongest" bond. I know my mother loves me and I love her a lot...especially since I lost my dad when I was younger.
Father/son
Mother/son
