Why was this question about Zabraks closed?

Question

This question has been closed as off-topic (asking about real-world science). The number of close votes in a short time suggests it was pretty clear-cut, but I'm struggling to see how it was considered to be about real-world science.

The question concerns humans, Zabraks, DNA and physical appearance in Star Wars. Humans and DNA are canonically in the Star Wars universe (and Zabraks are in Legends). There are canonical examples of heritable physical traits.

I note from comments elsewhere on SF&F that Star Wars "humans" might not be the same as real world humans, but I see nothing to suggest that the questioner was asking about the real world.

What have I missed?

Answer 1

Yeah, that's not a real-world science question. Quoting the established policy:

Any question that is asking for an answer within the context of a fictional universe, even if that question requires real-world science information, is on-topic.

Questions which are explicitly asking for an out-of-universe explanation of the science from a work of science fiction or fantasy should be off-topic.

The Zabraks question is entirely about fictional creatures; the only thing hinting at real-world science is the single word "DNA", and we've got hundreds of questions related to DNA, and even another similar question from the Star Wars universe. It wasn't even clear-cut in review, with a majority of users not voting to close; I don't know how it got closed so quickly, but I've reopened it as it's clearly asking within the context of a fictional universe (unless you think hybrid species created with human DNA are a real-world phenomenon).
