Well we all got to agree that if u crossed a blue dempsey (aa) with a regular texas (AA) the fry would be (AA,AA,Aa,Aa) right? meaning only half would have the gene that stimulates the production of iridescent blue cells BUT THAT WOULDN'T SHOW ON THEM. Now if you recrossed one of these hybrids that happened to have carried that specific gene (Aa's) with another (aa) male blue dempsey, you would get (AA,Aa,aa,aa) right? Meaning that half the fry would have it and WOULD SHOW IT because it's dominant on them...
So regardless of anything the first batch would look like hybrid between a reg jack and a texas. Although the second gen would have a similar fry but with half of them being "electric". It would be ore shaped like a jd because of it being 75% jack dempsey. But as you would keep the ones that had the most speckles and looked more colorful, the patterns would resemble one of a texas as they have the most.. colors would vary, but 50% percent of the fry would surely look " bluer " than the other half. IMO it'd be an extremely blue fish since the texas has a lot of it and a blue jd is the only entirely blue freshwater fish.
I'ma do it...you'll see! lol

Aye, that sounds about right.

If the genetics carry through across the hybrid (which has not yet been proven) then your description is not quite correct. If you cross an Electric Blue Dempsey (EBJD - bb) with a Texas (BB) then your resulting Galaxies will all have the same genetic make-up and they would all carry the gene (Bb). This is no different than how they breed EBJD's - you cross a Wild Type JD to an EBJD to get your Blue Genes or BG's, and then cross these BG's back to an EBJD. So if the EB genetics carry into the Galaxies and behave like the do in pure JD's, then your first generation will be 100% BG Galaxy (Bb) and look no different than other Galaxy hybrids, but they carry the gene. Again if the EB genetics carry through and act the same, crossing these BG Galaxy (Bb) with an EBJD (bb) would give you fish that are 75% JD, 25% Texas and 50% of these fish would be Electric Blue (50% bb & 50% Bb). Again, this is all theoretical. I am not saying it is not possible, just needs to be proven. They were a number of naysayers on the platinum JD's that it wouldn't work - that is combining the gold JD trait with the EB trait in the same fish - but that has proven to work just as expected. Give it a try and see what you get.

Oh yeah, actually this sounds about right. 100% Bb, not 50/50 BB/Bb.
 
Yeah u might be right about the percentage. The rest of it we'll have to see trying it. my only fear is that the EBJD won't have enough "balls" to withstand the texas when she does get in "heat". In the past I had a 6"inch male Paratilapia Polleni that jumped out of my tank after I added a 4" female texas just to see if they could breed, well she laid eggs that he couldn't fertilize even though he DID try it. She pestered him so much wanting babies that he committed suicide and I found him dry on my living room floor... =[
Now I made sure I got a good looking texas female but this time the most easygoing one from the batch I observed. My EBJD is about 5" inches and she is 3" so I'm keeping my fingers crossed. "and my tank covered all the way" lol
