Blood group AB, Rh Negative blood type is extemely rare among all the population. Because Rh negative blood is more common in Caucasians, it is found more in the European population than in those of Asian or African descent. However, I think there would not be a way to use blood typing for AB or Rh for proving anything about your lineal lines. Group AB blood, RH positive typing, is only about 4% of the population. Thus group AB with an Rh negative type is less than 1% of the population.

This is just my 2 cents worth. I am a trained Medical Technologist, and formerly worked in a blood bank lab in a hospital, so have some knowledge of blood types.

...proving anything about your lineal lines.

Absolutely there is. If you are the Barrack in a wood pile among a lot typical white people, political sarcasm intended, you might want to ask why. 99% of those people in Scotland and Ireland are 0 and you are not, reparations are needed.

I still remember shuddering a few years ago, when I spotted the car in front of me on the freeway.....it had two bumper stickers:

1 - "Give blood, the gift of life"

2 - a gay rainbow decal.
