As I replied in a sibling comment regardless of whether those biological traits have a real impact or not I don't think it's particularly relevant in this context. Maybe nature will prevent a black person from reaching Michael Phelps-levels of swimming proficiency but I don't think it would prevent anybody from learning natation 101. I don't think I'll ever win the 100m sprint at the olympics but I can definitely run 100m and probably faster than the average black person too.
