are electric blue JD hybrids

  • We are currently upgrading MFK. thanks! -neo
In that thread 3 weeks ago Grummie said that the DNA is the same as a regular JD's DNA but it's not. No DNA is the same there is totally different nitrogen base sequences for each fish because of generations of parents and offspring. It's basically if your grandparents are tall and your parents are short than each of the grandparents both carried a recessive gene for shortness and that showed up in your parents. Same thing as the coloration of the JD's. There is no possible way it's a hybrid at all. I think it started when someone spliced the DNA of a regular JD with a new gene using restriction enzymes to cut a certain nitrogen base sequence and replaced it with a blue coloration gene using DNA ligase. In turn changing the color and possibly the shape because of the new sequence. Then reproduced it until it became it's own definate trait. That's just my theory but it may be wrong. Also I think they die easy is because it hasn't fully established itself in the world yet because of the DNA splicing. In my theory I am saying that it is a man made animal but not through hybridization but through biological technology. This may be the case but if you know further information in this situation please tell. I could be wrong.
 
If it were man-made or DNA spliced, wouldn't we be seeing other species that have a freaky blue appearance? I'd imagine that there'd be EB angels, discus, oscars, etc. Why would someone start off with a JD?

My thinking was that it was, like many other fish, a mutation that happened by chance. Then, the breeder jumped on it & selected the fry accordingly.
 
I doubt anybody is putting the millions of dollars into splicing a fish :)

yeah and the EB would be the recessive trait, thats why there arent as many and the breeding prosess to get them is a lot harder. which makes them cost more :)
 
Read an article a few min ago that said they are hybrid.
 
heyy i was just throwin somethin out there. I mean i think it would make sense but yea people wouldn't spend all that time and money to something on a fish. Although they do it on bacteria cells so why not. I know they can definately create an artificial EBJD. It probably was a mutation since that makes the most sense really but my brain got a hold of me LOL!
 
Have some facts: www.bluejax.co.uk

Check the forum (http://bluejax.999.org) for a copy of the DNA evidence. We have no solid proof that this fish is not a hybrid (as the test that was used tells us nothing about the paternal line), but we can say 100% that it is part of the maternal lineage of Nandopsis octofasciatum.

The fins are elongated as a result of selective breeding from parent blues with long finnage. This may also explain the unusual body shape in some specimens. If you look carefully, most EBJDs have the same red edge to the dorsal fin that you see in normal jacks.

The ratio of blue offspring to normal and blue-gene-carrier offspring produced when blues breed with normals suggests strongly that this fish is a colour morph and not a hybrid.

The man that first discovered this fish (Hector Luzardo, now deceased) believed it to be a hybrid between the jack dempsey and 'Cichlasoma' managuense (the Jaguar cichlid) as that was what he was hybridising in his fish breeding facility. However there are a number of loopholes in his story that suggest he may well have been mistaken.

Links etc. are all in the forum.

Enjoy!
