Silver and black Arows breeding?

I can see a slight benefit long term in this situation. There is the chance to breed out the drop-eye gene by giving it Black Arowana Ancestry as well. It would take some time, but my guess it your fry would consist of some baby Silvers and some baby Blacks, with slightly different genes. Theoretically, and mathematically, 1/4 of those Silvers should lose the drop eye gene, and 1/4 of the Blacks should gain it.
Continue cross breeding the Black and Silver over time and weed out their baby silvers that don't end up having drop eye.
Start breeding those Silver without the gene and you should have a nice selling point.
This is strictly theory and may not work. The Silvers gene could be completely dominant and cross breeding a pair of a Silver and Black may only produce silvers, or vice versa if the Blacks genes are completely dominant.
There is a lot more to it than this. You may have to fool with Silver Male and Black Female, or Black Male and Silver Female. I don't know if the drop eye is a recessive gene or a dominant one. If it's a dominant gene it will be real hard to cross breed it out, and may not be possible at all. If it's recessive, cross breeding could eliminate it from some Silvers.
There is also the possibility, and it is pretty common in cross breeding in all kingdoms and species of animals, that the Arowana Fry could end up sterile.

Ofcourse this would all be for not if DE is not caused by a "gene". BTW it would seem that since blacks also get DE that they would also be carriers, if such a "gene" did exist.
Baby silvers don't get DE, most silvers don't develop DE until they are much larger. On average from my experience and what has been posted 15 to 18" range is where probably 80% of silvers develop DE.
Why couldn't drop eye be a genetic predisposition that is influenced from the the particular surrounding environment owners put them in such as housing them in small tanks, feeding them fatty foods, etc..? Not saying those are the causes, but there are many different things that can influence the Arowanas phenotypes... not to be confused with their genotype which is hereditary.
not for nothing, but while were on the topic of de, do silver arows get this in the wild, or is it something that occurs in captivity? I feel its what the arows eat that's a main factor-whether the food floats, or sinks-and is live-I think the ones that are feed live/foods that sink are what causes de...
I've read many different things of what causes drop-eye. Some say it's from over feeding fatty foods like goldfish which cause fatty deposits to form behind the eye. Others say it's because they got used to looking down for food, etc.. Whatever it is it seems it is from some type of environmental stimulus, hence genetic predisposition.
I have no idea if they get it in the wild.

I bet you could breed a black and a silver. but all you would get is a poor looking black arowana with drop eye
