How can you get a leopard strain ?

[troy]

Hi

Have a question for you experts,
I have one leopard discus and a turq , if i breed these two then breed the babies when grown with their leopard farther will i end up with leopard baby discus strain .

Hi,
Sorry, I don't have an answer for you, but I would guess if each of the parents was from mostly True breeding strains, then you would get some looking like each parent. These would be your F1's. Now cross breed the F1s leopards to each other, or back to leopard parent and you should off spring that are a higher percentage leopard.... according to one breeder...you need to do this until 60% of your pairs offspring are leopards and then they are considered a true strain.

This is only true is the genes for leopard pattern are equally as dominant as the red turq genes.... That I don't know.

I probably just butchered the leopard genetics....but generally the concept here is accurate for fixing a strain.

Any body out there that has breeding Leopards... how much of a spawn is leopard? looking back I don't remember too many posts where people posted Fry from Leopards...does anyone have any?

hth,

Genetic is the subject I will never understand. I've studied and bred many generations of fish. Somehow I always have a bunch of rule breakers. I have Leopard X Canary yellow and Red Melons. I have 100% Golden Leopard and Leopard Red Melon. Not even one single turquoise with bar. I have to scratch my head in disbelieve. Most of my experience discus freinds have never seen a brood like that. Carol's Golden X Cobalt throws 100% golden. Explain that!!
Your guess is my guess. No body knows until you see the fry.

Hey Jimmy, as to Carol's fish, I'm no expert, but I'd take a guess that the Golden colour trait is a dominant gene over Cobalt, or maybe even all other colours (who knows?) If that's the case, no matter what colour strain she breeds with the Golden, all F1 would be Golden. But, if Mendel's theory holds true, then if you were to breed F1 X F1 at least some of the offspring would throw back to the other colour (in her case Cobalt). It's just that in the case of Discus, this "experiment" would take a few years to complete. It's a lot easier with fruit flies, but not nearly as much fun! ;)

From what I've understood from some breeders on this and other forums, the Pidgeon Blood gene is dominant over other strains. So if the Goldens come from PB (and I think at least some Goldens, if not all, are from PB), that could explain why some Golden crosses would be 100% Golden.

I remember seeing that pic posted. If Carol's babies turn out half as nice as her big Golden Papa....WOW
