I have recently gotten back in the hobby after many years away.
Whats the deal with the Electric Blue Jack Dempsey?
Not hybrid but a different gene?
Please explain or if there is a link to a good thread or two that explains that will do.
Thanks
 
It's no hybrid, just a breed between either both partially and naturally blue jds that have blue in the gene or just one of them has it in the gene.

These fish are naturally occurring and are nothing to be disgusted with
 
The electric blue gene is recessive. In order to get a ebjd, you would have to breed a ebjdxbgjd for a 50% mix of ebjd and bgjd. Or bgjdxbgjd for 25% jd 50% bgjd and 25% ebjd. The ebjd fry grow drastically slower than their siblings and have to separated at a few weeks age.

I just want to understsnd the breed. If you have male and female EBJD and they spawn do you get same. Or do you have to breed one with a different JD to get the EBJD.
I have read just enough to be confused.

Why can't life be more simple:)
 
Just for clarification...
ebjd= electric blue jack dempsey
bgjd= blue gene jack dempsey (looks like normal jds but carry ebjd gene)
jd= well is pretty self explanatory :D
 
Not, to bad just need to know how to do punnet squares and have a basic grasp on genetics.
 
It's like basic 7th grade biology lol.

For the color morph trait, there are two alleles (which are each like half a gene).
An electric blue jack demspsey has 2 electric blue alleles
a normal jack dempsey has 2 normal alleles
a "blue gene" JD has 1 normal and one electric blue
Because the electric blue trait is recessive, the fish only has the electric blue color if it has two copies of that allele; a blue gene JD looks identical to a normal jack dempsey. The only way to know if you have one is if one of the parents is an EBJD.

So if you breed 2 EBJDs, you will get all EBJD fry, because there is no normal color morph allele to pass on to the offspring.

Is the last sentence correct?
