Well, I am retired, now.
For what it's worth, I have never claimed that I was a professional scientist or geneticist. I have stated on several forums that I have taken a University genetics course and that I have been a technician in a university genetics lab. I did get my name on a couple of genetics papers as junior author, though. And up till a few years ago, I could run snake genetics questions past one of my bosses at the lab for the real professional take.
As for using wild type vs normal, I would prefer to use wild type, too. It is more precise than "normal". But this is not a university or professional setting. IMO, jargon with a precise meaning must often give way to language that is less precise but more easily understood. YMMV.
