Unless... 2 doses of the Dominant Black is fatal.. then it works with what we know.

Theres also a tidbit of info that says breeding black to gold gives you better quality blacks.. hard to understand why that would be if Gold is recessive to black
Makes me think multiple genes are involved.
I also wonder on the chronology of the traits.. Gold has been around a very long time.. Black Im pretty sure is relatively new...

Not sure which 'those' you are referring to. Here's the math:
BB = Homo black
By = Hetero black
yy = Gold
BB x BB = 100% BB black
BB x By = 50% BB black, 50% By black
By x By = 25% BB black, 50% By black, 25% gold
BB x yy = 100% By black
By x yy = 50% By black, 50% gold
yy x yy = 100% gold

From the posts I read from Coralbadit he was working on the black rams since 2017 and he got his stock directly from the creator of the black ram Shahar Danzinger in Israel. I have texted with Shahar when I started and he told me he had Rams that only spawned just black but he did not sell those. Golden goose!!

Has anyone else that any of you know bred black to black and gotten all black?
Liz, brian, chuck, me .. none of us. Id think at least one of us would if Black was dominant. I have 4 pairs black x black right now.. none throw all black.

True that black to black throws a large percentage of golds. Jack Taylor is breeding some gold to gold that I gave to him and we believe they are throwing all golds but it's too early to tell. Black x Gold... I will try that as I have plenty to experiment with. I've noticed that some of my 2nd generation blacks are producing some blue and gold in the bodies of young adults, which may tell me it's weakening the strain. I like the development or simplicity of the genetics and since they have a fairly early gestation cycle and I'm interested in acquiring some wild Bolivian's to cross back to blacks, then back to blacks to see what happens...
I think Liz had all black once.

If the above is true, and nobody among you has bred black to black and gotten all black--it is unlikely, odds-wise, that none of you ever chanced upon a BB to breed--so then we'd be talking black being incompletely dominant (to gold) as a likely scenario. But since gold x gold from black parents does not produce black (confirmed elsewhere on the net) gold is recessive to black.
The only rams I've ever bred were wild. I assume wild coloration is dominant to both black and gold.
why? Its definitely not like that with wild discus...so I am not sure it would be with other cichlids.The only rams I've ever bred were wild. I assume wild coloration is dominant to both black and gold.
I have seen photos of german blue rams (wild type) crossed with black rams... the result is a mixing of the two forms.

I'm asssuming that if this is a one-locus affair, that the normal allele would be dominant to the mutated black and xanthic alleles at that locus. BUT if this is a multi-loci affair, well, that's an entirely different discussion. I did find this elsewhere, a response from a ram breeder to a question about breeding wild-colored ram x black ram:
"The pair shouldn’t breed any black rams, unless the normal looking parent has black ram genes"
Which might explain the rams you've seen.

Currently I have wild rams, black rams,gold rams and dutch blue rams here. I guess I need to do a bit more work but its been an interesting discussion! Thank you all.

Will be curious but it seems plausable that the B allele chromasome has developed a companion recessive lethal gene. Partially explains why By x By is 1:1 gold to black. Even with a recessive lethal on the B chromasome that would yield 1/3 yy gold and 2/3 By black (not the 50:50 most report) unless even one B allele is somewhat deleterious. As to whether or not B is recessive, has anyone thrown a black from 2 gold parents? Has anyone gotten all gold from a black x gold cross?
Has anyone noticed whether black x black broods are in general smaller #s?
