Basically, what I'm asking is, would it be possible for someone of Altmer bloodline to be a descendent of someone of Bosmeri blood?

Are Altmer and Bosmer basically Elven versions of real life human ethnicities, like Europeans and Asians, or are they completely separate?

Like all mer, they descend from the Aldmer.

And yes, it is possible for an Altmer to have Bosmer ancestors. However, he/she would probably be considered "impure" in the Isles.

Though the Altmer appear to have a tolerance for the Bosmer. They think of them as a lesser race, but at least they aren't humans or Dunmer.

Thank you for the reply.

I ask because, if I create an Elven / Mer character in Skyrim (very possible), I'm thinking of having him be a descendent of my Morrowind character, which was Bosmer. It was always kind of the roleplay that I had with my Morrowind character, that there were other "heroes" in his bloodline. Not a noble bloodline, just a bloodline with specific talents.

I had created a secondary character that was supposed to be the brother of my main Morrowind character. I downloaded the Moon Elf race mod to represent the character, because the character was more arcane than my Bosmer character, but at the time I didn't like Altmer.

I do like the way the Altmer look this time around, so I am debating between Altmer and Bosmer, and I was thinking of recreating my Morrowind secondary character, and turning him into a descendent of my Morrowind character, and was wondering if that'd work in the lore as an Altmer descendent of a Bosmer ancestor. Thanks for the reply.
