RealTalk, Rock is obviously more closer with his Samoan side than his Black side. Also, you never see him mention or pictured with his dad as much as his mom.
I know it's fun to dump on Rock with the jokes, but he's never shyed away from mentioning that his dad is Black and that he's half-Black.
He's obviously closer to his mom b/c likely his dad was always gone. So he grew up with/took after his moms side of the family because he was with her all the time.
In those days, wrestlers traveled 300+ days a year. He probably went months without seeing his dad at times.
