Not 100% true, there are small genetic differences between the races. It's why we have different skin colours to begin with.Nothing that should suggest separation, inferiority or anything like that. But it's not a strictly cultural difference.

There are small genetic differences between groups, but not any differences significant enough to divide 7 billion people into three or four races (which we do here in America). So, yes, 100% true.

Saying that there is no such thing as race does not mean there is no genetic variation. It just means there is no such thing as race.

Edit: Also I wanna add that we don't have different skin colors because we're different "races" (another flaw in the racial system). We're different "races" because we have different skin colors.
