Are there causes for a weak chin other than genetics...

Are there causes for a weak chin other than genetics? I look around at my family members and they all have larger more defined chins than me even my mom and sister. What gives? Is this my punishment for being a low test beta growing up?

Mouth breathing

this guy has the weird baby face all greek statues have

Just suck the BBC for jaw gains, like your mom and sister did

he does look greek
hair, forehead, nose everything

Dunno if you're calling me dumb (would not be wrong) but my brother had his mouth hanging open all the time when we're growing up, especially watching tv whereas I kept my mouth closed for muh superiority and he's got a way stronger chin.

Not calling you dumb. Sounds like genetics just fucked you over

Is right pic supposed to be after surgery or

Idk if this is true or not but qhat ive noticed is all the people ive played football with have very strong jaws and thick necks including my self
