well i thought that since I'm going to start my EBJD breeding project i might as well make thread as to how you do this.
The EBJD (Electric Blue Jack Dempsey) isn't a easy cichlid to come by. they are some what weak and need lots of care and maintenance to keep them happy and healthy. thus the reason they cost so much in LFS.
Breeding
why im doing this. well there are a few reason for why i have chosen to do this one is because these cichlids are rare and aren't the best quality. they are weak and are in need of new blood so that the future EBJD can be strong and healthy. my over all goal is to create a strong strain of EBJD to introduce into the hobby we know and love.
How its done:
this is the hard part. there have been a few ways to produce EBJD, but so far the main way is to take a regular jack Dempsey and cross it with a EBJD giving you 100% blue gene genotype jacks, now these guys look just like regular jacks but carry the blue gene, needed to produce EBJD.
next you take a blue genotype jack and breed it with a ebjd.
{now i have something very important to say to any looking to try this at home, DO NOT INBREED THESE CICHLIDS this make s the already weak EBJD even weaker!!!!! we do not need this in the hobby.}
back on track you cross the EBJD with a Bg (blue genotype) giving you 50% EBJD and 50% Bg
to further demonstrate this process i have found a punnet square on bluejax.com for all of you
electric blue gene 'b' and the normal gene (which is dominant) 'B' then the male has the genotype 'bb' and the female has the genotype 'BB'.
If we put this into a Punnet square (below: male on the top row, female in the left left column) then the proportion of each offspring genotype can be seen to be 100% Bb.
you can view it here http://bluejax.co.uk/breeding.aspx
All the fry will be heterzygous for colouration (i.e. carrying one normal 'B' gene and one electric blue 'b' gene), meaning that they will look like normal JDs, but be carriers for the 'b' gene.
To get EBJD fry, a female from this first spawn must be reared to breeding age and then mated to an EBJD male (preferably not her father to avoid inbreeding problems).
This will produce the following offspring proportions:

So 50% of the fry will be Bb and look like normal JDs but carry the 'b' gene for electric blue; and 50% will be bb i.e. EBJDs!
i hope this hekps all of you to understand EBJD breeding a little more
