Has anyone performed this cross yet? Interested to see if the Albino gene in the
Dantums is the same gene in non-related Albinos.

Albino is Albino.... crossing an albino dantum, to say just a silver albino...yada yada ??..or other non dantum?...will get you albinos that are 'het' for whatever else a dantum is...??
The albino gene from the Dantums could possibly be in a different loci, as is the case with albino ancistrus. Two albino ancistrus when bred together can produce non-albinos, that is not uncommon to hear of. The same could be possible with angels. If the cross is made and all offspring are albino then your statement would be true, an albino is an albino. However, if the cross is made and non-albino offspring are produced then it would indicate an albino gene in a different loci. See where I am coming from?
From Steve Rybicki, "I suspect that the albino gene that the Dantum comes with, is on a different location than the albino that has been in our angelfish stock the past 25 years. It appears to interact and look slightly different."
I tend to agree. Out of curiosity I was just wondering if anyone has explored this further.
So, until we see an Albino Dantum X Non-Dantum Albino cross, the question lingers,,,,
i respect Steve's opinion, but I'm leery of an observation opinion in this , I'm surprised that he, or Carol, who does some things with David's stock, haven't already done the cross....?? I agree, it'll be interesting to see the results...Quote:

I was thinking that it would be one of the first crosses attempted. Whomever does the cross would not only isolate the new albino gene but the new loci as well. That is of course if they exist. I'm not a fan of the Dantums or I would have done so by now. I am however interested to see what comes from such a cross.
In the case of dual/distinct loci (i.e. albino locus A1 and albino locus A2 for clarity) the result will be silvers +/A2 - +/A1. F1 sibling cross will produce (at least in theory):Quote:

There has now been a least 2 reports of a albino dantum X non dantum blood albino cross that produced all non albino offspring.
Correction,i believe one cross used a het albino dantum,bred by the guy who did the later cross.
Yes, it is true there is something different about Dantum Albino. Crossing it with any other type of albino will produce non-albino offspring. If anyone is currently undertaking such a breeding program, please document it and share.
