DNA tests do not detect admixture events beyond 250 years.

Only if a haplogroup is from a different regional origin, can they suss out if a person’s heritage has foreign roots. If the present haplogroups are overwritten, to reflect a local origin, the person will score as if they’re local, to any given area.

Example: West European man takes a South Indian bride 300 years ago. A son is born, he has his two parents X and Y haplogroups respectively. He gets married to a West European girl, and he has a son but no daughter, and on and on, but his family never introduces any foreign haplogroups ever again, and all the individuals the descendants married, never intermarried any person of foreign origin either.

So a modern descendant will not have any haplogroups that point to anywhere, except local West European origin. The admixture test can no longer detect the South Indian influence, because grandmother’s DNA was introduced so long ago.

But phenotypically or physiognomy wise, there might* be some lingering differences from “pure” Western Europeans. I doubt anyone would still be able to notice any difference, but it’s possible.

This can happen with women taking foreign husbands too, the haplogroup evidence can be erased, as long as the sex of the child, is different than the sex of the foreign parent. Otherwise if the sex of the child, matches the sex of the foreign parent, and the chain remains unbroken, the transmission of the haplogroup will remain constantly detectable, until an opposite sexed child is born.

People in general forget that Spain and Portugal were occupied by Moors 1,300 years ago. Their presence permanently altered the population of the Iberian peninsula.

If a Spanish person’s family lost the Moorish North African/West Asian/Sub-Saharan African haplogroups, and haven’t reintroduced them into their family gene pool, in the last 300 years, it doesn’t change the fact they probably have non-European roots. Even if it’s no longer detected through an admixture test, the foreign DNA is still there, it’s just older than current methods can detect.

There’s a distinct difference between Iberia and the people in my example of a single admixture event. Where the single event family, probably had their foreign phenotypic traits erased, and Iberians did not lose the traits.

In Iberia, the admixture event occured dozens, to hundreds, if not thousands of times. Children of the admixture events spread non-European genes all over Iberia. The peninsula’s population has been trading and swapping and keeping the traits alive and present for over 1,000 years, they can never be erased because of how ubiquitous they are.

It doesn’t really matter in the grand scheme though. 4,000 years ago East/Central European men replaced the local Iberian men, and no one really cares. That probably changed the look of the people as well, but it’s another admixture event, lost to the sands of time.

Long story short Iberia/Spain/Portugal is full of people with non-European/North African heritage and it shows on their face, even if a DNA test says their heritage 99% European. The tests simply do not count for heritage beyond 250 years, and unless the haplogroup is foreign, there’s no way to tell through genetic identification. Unless you’re some ethnic identifying maven.

Or maybe her family’s sliver of sub-Saharan African and indigenous American heritage was very influential on their traits. ¯\_(ツ)_/¯
