Marlon Wayans has a perfectly good explanation as to why his 12-year-old son is such a terror on the b-ball court ... the kid's actually father could be NBA star Steph Curry!!
Remember people ... Marlon is a comedian.
We got Wayans leaving Equinox in L.A. when we asked about his son Shawn ... who's freakin' dominating the middle school hoops circuit these days.
Check out the clip -- Marlon says he has absolutely ZERO hoops talent ... so there's only one way the kid could be so deadly on the court ... the DNA of the best player in the league.
Now that we look ... there is a slight ... naw.
