I am attempting to get my Almost all white F2 Midas male to pair with my F1 Carpintis Vontehillo female. I want to see if I can get the white gene from the Midas to carry over and try to maintain the pearls from the Carpinitis.

I am just curios as to how likely I would be for this to happen? And has any one else (Im sure some one has) done this. I know some people use this combo as part of their Red Texas lines but have not found much on Midas x Carpintis hybrids.

Dozer my male midas has paired with two other Female Midas and has breed and seems to be showing interest in the carpintis already but not paired yet. I dont think it will take more than a few days. I am not looking to sell or bloody the gene pool as some think. This is more or less for my own curiosity and the fry will most likely never leave my home, and if by chance they were to I would make sure that it is well known they are Hybrids. Most likely perhaps all but maybe a few will end up feeders unless I get a few that show sign of being easy on the eyes then I may hang onto them to see how they turn out.

Any way does any one have pictures of this being done before or what to expect from it?
 
I will mention, I have looked into this but all I have found is pictures of the parents, never what the off spring turns out like.
 
You said when that you've had the male breed with another Midas, did this white gene show up in any of the fry? When you're trying to isolate a certain trait in a fish you first have to find wether or not its a dominant or recessive gene by breeding the same genotypes together to see if it carries over. Then take the offspring that have the gene you're looking for and breed them with another fish (like your carpin) to try to get that specific trait to carry over. This is vary vague I know, but just an idea of what to look for and do. A good book that'll help you in your project is "Genetics for dummies", this will give you a better idea of genetics and isolating genes or traits to alter genetic codes so to speak.

I gave some of his fry to a friend who is growing them out right now. They are just starting to peal out of their baby colors so I am not totally sure. I do know that the batch of fish he came from though was either all white or mostly white.

I will look into that book.
 
The Midas in my picture is the One I am talking about. He has lost about half the orange he has in that picture now.
 
Alright, thanks. I bailed on the idea. The Male Midas and Female Carpintis wanted NOTHING to do with each other lol. They would stay on opposite sides of the tank and only came near each other on the rare occasion the male would chase her away.

O well. I am selling the Carpintis to buy a group of 8 2 inchers, I will get a pair (hopefully) and just keep a pair of Carpintis.
 
IMO
they fade like this:

barred to pale orange, then they brighten up..
Then after that if they have the white gene, the white start to com in and pushes/compressing the orange in their areas.

white is a phase after orange. It's a farther stage in fading that only if you breed to another fader you will get the white in.. The 3rd/or white phase will not come in if you cross with another non fader.. When you cross to a non fader, u move the fading gene backwards so you wont reach 3rd phase.

White stage is a fader extreme stage ... And I think two fader genes can make it happen and one of them must have the white phase gene.

U get a batch full of them or most o them if both parents have white genes.. But they get white later. Not right away
 
The white gene is an incomplete dominant that I've only ever seen combined with the fader gene, as we know it in midas or red devils. You should see some white markings in these fry, but the more the gene is paired up the stronger it becomes. When animal guy spoke of different phases he was correct, each time the gene is paired up the results are exponential, and way more dramatic than you might think. Fish with a higher percentage of white produce even whiter fry, if two low whites are bred they should throw medium whites, if two medium whites are bred they should throw high whites, if a high white is bred to a low white you could get anything ranging in looks between the mother and father, but probably not quite as nice as dad. Bred to a fish not carrying the gene the number of fry expressing the pied markings will be small, save them back to be bred to their pied parent or to each other...in this case to their parent, I doubt you will get fertile males from your proposed cross.
 
I didnt know any one had left any more comments on this one lol.

Well I have the group of Carpintis, 9 total right now. The best looking male and female are going to be kept as a breeding pair but then the rest are either to be sold/traded so I may try to attemp this later on any way.

Thanks for the info on the white gene. The male Midas I have is mostly white with very little orange on his tail and fins. I picked up another female for him as well that is mostly white with an orange cap on her head and small markings on her tail and fins like the males but even less. I am thinking maybe later on after I Get my breeder pair of Carpintis "Escondido"s and get viable fry I may try raising a group of Carpintis Fry and Midas fry out together when the time comes. How ever the Carpintis are still quite small (2-3 inches) so it might be a while.
