In regards the 1% of ancestry from
Africa and another 1% from Asia, the way I understand it is if we look
at a family tree for a person, it takes 7 generations back to get over
100 ancestors. At that level we have 128 if they are all different
people. Of course, if any cousins married then there are actually fewer
separate individuals.
Since for my father, I know all
his ancestors well beyond 7 generations back in the Azores, the only way
to have an ancestor who was from from Africa or Asia must come from our
ancestors in Chile, where we know only 4 generations back so far.
Since
5% of his DNA says it's from the native population of the Americas and
the most recent ancestor from Chile was 3 generations back where there
are just 8 ancestors, 1/8th of his DNA should be from Chile which is
12.5%. If we say some percentage was from Spain to account for the
Conquistadores and if at the 7th generation there is one from Africa and
one from Asia, plus 5 who were natives, that leaves about 7-9 who were
Spanish. That works out OK. It's a real life algebraic problem - don't
see that much.
But it's not really that simple,
because I'm sure the Conquistadores married into the native population
early on from the 1500s forward and so there are tiny percentages from
each generation that are accumulating as we reach to the 7th generation
for my father - that is the late 1600s for his Azores lines, so would be
something similar for the lines in Chile. And so maybe there are many
different lines of African and Asian ancestors which all together
account for about 1% of his DNA for each of them.
The
only flaw in that is the fact his DNA was identified as from a specific
part of Africa. If there were many lines, it would also seem there are
many different parts of Africa. I hope some day I can trace them back a
little further to resolve some of this.

My father also got a similar surprise - 1% East African Pastoralists which the map shows as Uganda, South Sudan, Kenya. I suppose it comes from a slave. We have one exposta from the late 1600s which might account for this mysterious DNA.And it was interesting to see he has 6% Middle Eastern in the area of the Berbers - North African Coastlands.So my own 4% Middle Eastern in the area of Eastern Afroasiatic which the map shows as Jordan and surroundings must be coming from my mother's side. I guess this is because of the Turkish invasions into Hungary through the Balkins, because my wife, 100% Slovak has 6% of this same DNA.And my father also has another big surprise - 1% East Asian and specifically Asian Northeast which the map has around Korea and Japan and into Russia.My guess is the 1% African and 1% Asian must come from a couple slave ancestors.Very fascinating.Doug da Rocha Holmes
