Well, as far as I know, the amount of white is not passed from parent to offspring. Case in point:
Daddy:
Son:
Both of the pieds he has fathered so far were at least 50% white. And mom is only a het.
I've seen low white males as low as $450, and high white males are usually $150-200 more. Low white females I've seen at $700, high whites at $ 975-1250.
