What causes a recessed mandible?

Harry Kane and myself both have bad CFD. Yet Kane doesn’t have a recessed mandible while I do even though we both have recessed maxillas. My guess is that it has something to do with incisor inclination or is it genetic size of the mandible?

Here is Harry Kane:

Here are my incisors:

Orthotropic doctrine usually attributes a recessed maxilla + normal length/long maxilla to a low tongue posture. The palate narrows as a result, the maxilla becomes recessed, but the mandible grows forward as a result of the pressure of the tongue.

I am sure that there may in fact be a genetic component to mandibular length, perhaps somebody else here can speak to this with some data?

I agree although he has CFD, he looks good and his mandible is good.

yeah but if the maxilla drops so does the mandible because the mandible is connected to maxilla

Mandible size is tied to genes I am sure but also to muscle tone and usage of chewing muscles. Also, you seem to have a pronounced overjet. Maybe he does not.

This is only a problem if the maxilla is overly clockwise rotated.

In my opinion, the maxilla carries facial attractiveness the most. Cheekbones, hollow cheeks, better eye area, it even has a big role on the mandible, facial height, there are more reasons, but I cannot remember them. 

It is a bit of a dumb argument, would you rather this or that. Recessed mandible with forward maxilla and vice versa. We all probably have seen both and comes down to which one you subconsciously think is more attractive. I don't know which one I like, which one is more preferable, and it all comes down to what you like at the end of day.
