Does anyone have a good handle of the electric blue JD genetics? I hear that you have to breed a "het" with a "het" to get babies, but a double homozygous pairing wont produce electric blue babies. Is this true, and what is the mechanism for the expression of the gene(s)?

That is an awesome question, but unfortunately I can't answer that. I will promote your post so hopefully you can get an answer, but I don't know how quickly. That would probably need to be answered by someone with both fish and genetics background. I don't know if we have people visiting here with that sort of background. I look forward to reading the answer though. Have you tried to search the web for Jack Dempsey genetics?

I have looked, but haven't found much information about what is exactly going on. The statements all say that EB to EB pairings result in normal looking babies. The next parts are a little more confusing. They say either that you can pair an EB with a "het" or you have to breed two "hets". I added the quotes because they obviously aren't true hets in the simple recessive sense of the term, but most people would recognize it as a descriptive term, if not totally accurate. Thanks for the publicity.

I really wish I could help you interpret, but my genetics background is very weak. I only had one general genetics class, so we really didn't cover things like this, but if you will notice it says HOT TOPIC by your post. That means your post had been promoted. I hope you get an answer quickly.
