Manute Bol's 7 Ft Son is Dominating Puny Humans At 16 Years Old

Guess the apple doesn't fall far from the tree ... especially when that tree is FREAKIN' GIANT ...

TMZ Sports has exclusive video of Bol Bol -- son of late NBA player Manute Bol -- hooping against some high school competition at a recent high school hoops tournament ... and it just ain't fair.

Manute was one of the tallest players in league history at 7'7" and his kid, Bol, is already 7 ft -- AT 16 -- which is why peeps we talked to at the tourney say the kid is a lock to be a future NBA lottery pick.
