Here's the rundown:

1. I inbred 6 generations (the original fish count as f1) of German Tuxedo --
starting with a Yellow-tailed male -- until all the male offspring were dark
yellow.
2. I inbred 7 generations of Red-Tails until all male offspring were Cherry
Red.
3. Using females from the last generation of Cherry Reds and males from the
last generation of Dark Yellow Tuxes, I crossed the 2 strains. A large batch
(15 fry: 6 M, 9 F) yielded males that were ALL a color combo I'm calling
"Sunfire": rich yellow tail with tinges of orange and a bright light blue
peduncle.
4. I inbreed 4 of the Sunfire males with 4 of their siblings. The results?
Hang onto your hats!

Out of 8 batches of fry, I matured 2 to get a reading on where this cross was
going. The two batches totalled 11 males. Here are the traits displayed:

(1) male is SILVER
(1) male is SILVER TUX
(1) male is PINK w/BLUE peduncle (like in the photo)
(1) male is SUNFIRE
(2) males are SUNFIRE TUX (one in each batch)
(2) males are BLAZE TUX (a fire-engine red, one in each batch)
(3) males are FLAME (like Sunfire, only deep orange w/blue peduncle)

I make FIVE tail colors there. How can that be? If you do the punnet square
thing, shouldn't there only be FOUR possible combinations?

Gosh, I'm really over my head here . . . .

Greg, you understand the theory very well. Do you have any idea what I'm
dealing with here?

Thanks,
Clarissa
