They do look really great. I just dont know how to put pics up on here. If you can tell me how I would love to post pics.cichlidfish;4118345; said:

Gold Dempseys are Leucistic... Leucism is a condition characterized by reduced pigmentation.Blankmanrl;4115110; said:
Yup...Blankmanrl;4115110; said:
It is "naturally occuring", meaning it is a genetic mutation that happened on it's own without human manipulation...Blankmanrl;4115110; said:
Once a Leucistic (Gold) individual was obtained by a hobbyist/breeder... They were logically paired off with other specimen to produce more Leucistic (Gold) fish. This is nothing more than "line breeding" or "selective breeding", not any kind of hybridization or genetic manipulation.
Blue Dempseys, just like Leucistic Dempseys/fish/animals, just like albino fish/animals, just like tens upon thousands of naturally occuring thoroughly researched and documented traits... all follow Mendelian Genetics...TrikkyMakk;4115220; said:
It is very well known that when we hybridize two species of fish... some offspring will look like the father species, some will look like the mother species, and there will be a very very wide variety of blends of the two...
It is very well known that this is NOT the case with Blue, nor Gold Dempseys.
It is very well known that Blue and Gold Dempseys both follow the exact pattern that Mendelian Genetics predicts, which is the absolute most common form of passing genetic traits within a species.
I would encourage you to refer to them as Leucistic to help promote accuracy in our termonology... "Common names" so often interfears with proper understandings...auratum;4115436; said:

I'm thoroughly convinced that a single specimen cannot be both Blue & Gold... I elaborated on the science behind my belief in your thread about your fish...Blankmanrl;4117551; said:
Although absolutely no offense to you nor your fish... nor it's breeder. I just think it's going to blossom into a typcial Blue Dempsey... which is an awesome fish!
I don't mean to sound like a "know it all"... I've just put a lot of time/energy researching this topic over a number of years and wanted to share what I've learned...
We need to be careful with any label we give them. I don't agree that "Gold JD's" should be labeled "leucistic". Each mutation can be very different. You are assuming that what you have read about "leucism" is exactly what is going on in "Gold JD's". The only thing I see that is different is a reduced amount of the dark brown color (melanin). I have seen lighter brown pigmentation expressed with mood as well as yellow/gold, pink/red, and the blue/green spotting that is typical of normal JD's. From your definition of leucistic, it sounds like you don't believe they can express most colors, but the only color I see reduced is the dark brown color.nc_nutcase;4121095; said:
We can't assume a gene mutation in one animal is the exact same as another mutation in a completely different animal. The Mendelian genetics apply, but the limitations on what colors are or are not present is dependent on the specific mutation to that specimen.
As I posted in the other thread also - time will tell if 74Ray has successfully combined the two color forms.
