Much more likely, considering the lack of input from non-European populations in those genetic databases, that the Portguese got around in West Africa as well, so you're sharing some Portuguese DNA with West Africans, not West African DNA with the Portuguese.

...that's what I said? The sailors got around. My Portuguese cousin said that somewhere back in the family line was a distant great-something-something who was likely Black, if family gossip is true, but the records are thin on the ground.
*shrug*

It is what it is.

I think they were saying that it could be your great great great grandfather had kids in Africa and kids in Portugal with different women, and enough sailors did that to skew how the database classifies certain genetic sequences.

So, the genetic sequence(s) identified as West African could actually be Portugese in origin, but are misclassified because not enough West Africans with non-Portugese ancestry have added their DNA to the database for the genetic sequence to be identified as not being indicative of West African ancestry.
