Investigating my family's bizarre MENA admixture.
Since i did my first DNA test, one thing that surprised me was tha huge MENA admixture that i always scored, generally around 5 - 10%, which is pretty high for someone with zero recent ancestry from any place other than Brazil and Portugal. After i tested both my parents, that just got more confirmed.
For some context, my dad is 7/8 colonial and 1/8 portuguese, my mom is 100% colonial, in my family tree my paternal side is better documented, my maternal just reach about 1850's in most branches, but, as far i gor, they both have a pretty normal background.
Using our simulated coordinates from K36 to g25:
*Obs: my mom's raw data have a low coverage, but the results looks ok anyway.
1°model) Know modern ancestry: SSA + Native + Portugal + Andalusia

The distances are good/ok, my native seens a bit a low, but nothing crazy.

The distance drops a lot, i get 15.8 MENA, my dad gets 12.4 and my mom gets 10.8, despite that the MENA is eating the SSA a bit, thats just crazy, is like my parents were both 1/8 MENA in origin.
Things get even crazier in IllustrativeDNA, where i got 22.2 MENA, and got better distance with corsican than even portuguese or Canarias in a 3-way.

I also did a average of my parents simulated coords, it has less MENA and a better SSA/Native % than my K36/Simulated coords, looks much more like my oficial g25 coords from IllustrativeDNA/Davidski.

My dad's real coords from DNA Genics also looks a bit better than the K36/Simulated ones.

The interesting thing is that my g-grandma (the maternal grandma of my dad) simulated coords seens very normal, she scores a low MENA even with simulated coords (that seens inflate a bit the MENA), ironically in her genealogical tree she is possibly descendant of multiple jews from Bragança, and also her "mother Y-DNA" is of north-african origin.
Code:

Soon i gonna test my paternal grandpa or maybe my maternal g-grandma to see if they scores that MENA too . . . Overall our family seens very "mourisco" admixed, generally using a 3-way or 4-way model we always get the best distance with Canarias + SSA + Native, in ancient models we always score a lot of Al-Andalus, Imperial Rome or Punic. Very interesting.
Does any latino/iberian get similar results? :muslimcomputer:
Btw, here our coords if u wanna try:
