I have no idea what you would get...however I can give you a little rundown on genetic basics. Should they breed and you get the offspring up to a little size, I would see if there all a match, a few like each parent, all like one of the parents...and take notes. This will give you a basis for how each gene or patern is passed on. assuming there isnt an issue with a patern or color being connected to a tank condishion (and believe it or not with some things that is true) with a few spawns you should start to have an idea.
in its simpleist form, genetics comes down to if a trait is dominate or resessive to another similar trait (color for instance) one color is usualy dominate over another. assuming this rings true, you would have all offspring who "look" like the dominate color (or patern) but are carriers for the other. 100% and called an F1 generation.
lets use black and white as our colors (easier to fallow), and black is dominate over white. your black specimen would have a genetic code of BB(black and only carrys the code for black). one letter stands for what you can see, the other for what you may or may not be able to see. our white specimen would be ww(white and only carrys the code for white)....there offspring would be Bw (black but carry the trait for white though we can not see it) a true F1.
now lets breed 2 of these fish. each parent fish is now an F1 and black but carry the gene for white. we would get, on average, 25% BB, 25% ww, and 50% Bw...this is called an F2 generation.
I should point out that we KNOW the results because the fish are related and we know that the genetic markers are on the same alli. should we breed 2 F1 generations togather who are NOT related, we may not get those results as there are hundreds of allis possable and the code for color may be across 2 or 200 different genes.
this is why is possable to breed 2 specimens with the same recessive trait and get totaly normal offspring. for instance there are dozens of albino genes in some animals and each is on a different alli from another. in that case we can breed 2 albinos ( recessave albinos) togather and still not get all albino offspring. this is why its crucial for fixing a gene to use family breeding.
there is also a form of genetics called quantitive inheretance. think of it as black and white on extremes...and grey in the middle. in that case our F1 would be grey....and the more we bred white to them, the lighter they would be, the more we bred black to them the darker. usualy this type of inheretance is found in preformance genes though, not color.....like how fast a horse runs or how hard a hound trees

and is realy just a formula for adding the results of several genes togather for 1 final score.
this is genetics at its basic level....and it gets far more complicated. Notes will come in very handy later on to not only record the results, but give you an idea of how to steer towards the final result your after.
