Geneticists are typically geeky (particularly those of that started out as fruit fly geneticists); once someone starts a fashion, people follow on. And that’s how it was with the naming of our genes.
My latest: phoenix
We name them after video games. Of course, it all began with the Atari back in the eighties. For example, there’s a gene called ‘sevenless’, because when it doesn’t work properly, segment number seven in the fly’s body is missing.
Following that a few geneticists discovered other bits of DNA, genes with similar sequences, and called them things like ‘son of sevenless’, ‘bride of sevenless’.
Mine, similarly jumps, hence 'phoenix'.
