Why hasn't MLK produced another MLK? Why hasn't Khalid Muhammad produced another Khalid Muhammad? Why Marcus Garvey didn't make another Marcus Garvey?
That's simply not how it happens bro. In sports it's more likely because that has to do more with genetics for strength, speed and etc but even that is a gamble.
Malcolm's daughter has done a lot of work but she ain't Malcolm level persay and that's besides the point.
The only example I could think of off top and she's not a rapper is H.E.R. Her father was a small time musician and she went on to do her thing with Rnb music. In fact it's more likely for singers that it happens that way but for the father or mother even to be a big time rapper then the kids comes out and is a rapper that makes it too is rare as fukk. Don't think we seen that.
