Answer 1

You might get better answers if you go under Science and Mathematics and then the subcategoryBiology or the subcategory Medicine.   In genealogy, people don't think in terms of blood types.  They really don't this in term of genetics.

Genealogy is tracing a family history one generation at a time with records.

Answer 2

Europeans populations are characterized by a low type B blood frequency and a relatively high type A blood frequency while Asians are characterized by a high frequency of both type A and B blood.  Type AB is more frequent in Asia than in Europe, but it's still the rarest blood type there or anywhere.  

The chart in the link below notes that 13 percent of the Tartars have type AB, so it's possible that you are a descendant of Genghis Khan.  Since  being Jewish counts as both an ethnic identity and a religious one, and the Jewish diaspora has spread Judiasm throughout the world, you might wish to have your DNA traced to see just where your ancestors have lived if you really want an answer to your question.

Answer 3

That blood type is also more common among Native Americans (Indians)

Answer 4

AB isn't as rare as it used to be. All of my kids from my first marriage are AB positive. I'm A positive and their dad is B positive. All of the kids inherited both proteins and it has nothing to do with ethnicity. As my obstetrician explained to my ex, A and B are only proteins. O is lack of the proteins. A baby can inherit either protein or both proteins from the parents. It's indiscriminate in the womb.
