Considering that Alex doesn't have the same physical power as Albert on her human form, she only gains that power after mutation and she canonically HATES mutating her body, then i think it makes total sense that she took Albert's clone and raised him so she can use him for her plans, and she encourages him to imitate Albert only because she wants him to be as powerful as him.
Especially based on Zeno's mannerisms and body language he's completely different from Albert despite being played by the same mocap actor, like:
Zeno seems to walk with more strutting and showing off than Albert.
He treated Grace more politely with a calm tone than his aggressive tone with Leon/Victor, that suggests Zeno is more respectful with women maybe because he's mommy's boy
His fashion with white suits might be an obvious hint that he's attached to Alex' fashion, Zeno is exactly how i imagine Alex' spoiled son would dress like.
Like everything about Zeno suggests he's definitely raised by a single mom and it gotta be Alex, their dynamic would be fun like a spoiled son and loving mom only because she uses him as a tool for her plans.
Alex' lore was never explored until RE: Revelations so i think the remakes now will definitely add her lore into the story, like we could see Alex in CV remake or RE1 remake, to see her whereabouts and what she was doing all those years.
