Dear Physics Forum,
Is there any model where the electron and quark share a fundamental relationship, maybe in some string theory? I ask because it seems too much of a coincidence that two completely
independent particles would have a simple charge relationship of 1/3:1 .
Thanks, Mark

Maybe you look at it the wrong way round. Charges are more fundamental than elementary particles. So there are different combinations of charges. An electron is some value of electric charge in combination with zero of baryonic charge, while a quark is a non-zero combination of both charges.
