I have a regular convict that has the recessive marble trait. I was wondering what would happen if I breed it to a carpintis... Could the marble or pink possibly show up with some pearls? I have a marble male I could try also but was just wondering about the recessive gene. Basically I was wondering do recessive genes only work within the same species?
Can recessive genes show when spawning hybrids?

I've been wanting to do that cross for awhile. I'm just waiting for my calico females to get bigger. My guess would be no it wouldnt show especially if your regular con is just a carrier for the marble trait. But then again fading is a recessive gene as well and you already have experience with that.
Thanks for that. I didn't know the fading gene was a recessive trait. Well I guess anythings possible. If my fish pair up I'll post pics.
Sorry but wrong fading is co-dominant not recessive. If you breed a convict without the gene for pink at least to a pink one none of the babies will be pink but when these are bred together some will/can be produced. Also just because a trait shows in one species does not mean it can/will be expressed in another even though present genetically. There is a topic on this forum about this concerning the fading gene not expressing when added to certain species that elude me from naming right now.
I have used pink convicts to HRP to get pink HRP's. I lost most of my breeders used for this but have one pink pair almost ready to breed right now. I also have crossed them to a green texas with the goal of getting pink texas to breed with red texas. The point is hoping to not need the peeling process to judge potential in my red texas hybrids while still small.
So to finish about the fading gene it is possible to get a few if one of the parent fish is homozygous born in the first generation. Just read on this forum all the members that have taken pure texas of either species and crossed them to one of the fading types and gotten a few fading ones first gen.

He knows his stuff so I just take his word for it. Now with hybrids it can be a whole different ball game.

Thanks for that info Gutted. Yup... When RD speaks on a subject you can take what is said as a given. Well I also have a bp that I might try and pair him with also. So then I'll be messing with fading/short body genes. Whatever I can pair him with I'll just run with it... After all it is his choice. Lol
fading is not recessive.
take a >faded< red texas from first generation for example. ( texas x kkp)
Certain traits can be recessive, depending upon its nature.
Recessive is essentially all relative - that is, a combination of allele A and allele B may mean that trait A shows, but if you have allele B and C, it may mean that trait will show. In general, it also means that if you have allele A and allele C, trait A will show.
In hybrids, certain alleles will not have a complimentary allelle (if the other parent does not have the gene), and therefore acts as a dominant trait.

It seems like others on here just look past the plain proof of what some of us on here are saying not by hypothesis but actual breeding results done by us not someone else on a fish farm not sharing how they did it.
So plain and simple many people have been breeding either texas species together and not getting even one faded or amelanism form produced, yet breed one of these fish to a species or hybrid with the fading gene and some offspring can be produced first generation. If a texas cichlid species already carried the gene in a recessive form then by now it would have already showed its head with so many people having bred them over the years. That is not to say that it does not lie hidden in some form in a group of fish somewhere in its native range.
Last to point out is in the non hybrid fading species the same proof can be seen/proven as they have non-faded forms found in the wild. When these non-faded forms are bred together no faded offspring are produced hence they breed true. Now take one of these and breed it to a faded form and you will get babies both ways. Those faded offspring only contain genes from one parent for it so are heterozygous not homozygous for the fading trait.
This is also why in the hybrids we can breed two faded fish and not all the offspring peel or fade. It tells us that our breeders are heterozygous for the trait or and this may be more likely that the fading trait takes multiple sets of genes to express and not just one complete set on one alleles.
