How likely is an Electric Blue Jack Dempsey?

If two normal jd's breed, the chance is zero. If you have two normal looking js's each carrying one gene for blue, 3/4s of the fry will look normal. A fourth will be electric blue.

If you breed two electric blues together, the resulting fry ought to all be electric but so far they all perish before completing development.

If you breed a male electric with a female that carries the gene but looks normal, you will get half electric and half carriers that look normal. The reason for choosing a male electric is that the electrics are weaker and regular males would kill an electric female, not for any other reason.

If you cross a gold jd with an electrc, all the offspring look normal but you cross siblings and get half normal looking, a quarter electric and a quarter gold. Because of higher mortality rates, you will end up with fewer electrics than this percentage by the time the fish are big enough to sell.

How do you ever hope to get an answer to that question on here?

The genetics involved in producing and fixing colour mutations in fish is complicated and it takes years of selective breeding to achieve such results, so you are hoping that an expert in the genetics of one species of fish is going to be looking at Yahoo answers.

Join a few cichlid forums and ask on there... you may get opinions, but I doubt you will get any positive answer.

My opinion is, evolution produces animals that develop their physical characteristics to enable them to thrive in their given environment. Why are humans obsessed with changing such things rather than standing back with awe and respect for what the power of time has produced in the natural world?

A normally coloured jack dempsey is a stunning fish... be happy with it.
