How do you produce a Blue Gouldian?

I just have to say, that was some of the best and clearest explanations for genetics I have ever read!!! Better than most found in biology books. Thanks for all the detailed info about the blue gene in gouldians. I have heard the "weakened" offspring occuring in a lot of morphs and even something called a "death gene" in carpet pythons which was really mind bogaling to think that if an animal inherits two of the same genes from their parents that they die at hatching...crazy! have you ever hear of this happening in finches? (sorry about my spelling, typing WAY past my bed time)

Not sure about any Finches but I do know that in Button Quail the Golden Pearl mutation is a lethal gene and will result in 25% of their eggs not hatching. It is my favorite mutation. I posted some pics of my unusual male. He is quite different. I wonder too if there is anything like this in any Finch mutation that anyone knows about?

Sad to hear about the lethal gene being in your favorite morph of button quail but it is interesting to know that it affects things other than snakes. Sadly, the death gene is found in one of the most beautiful morphs of carpet pythons, too. They found out with the carpet python that the "jaguar" morph is actually heterozygous (or "split" in bird terms) and that when you breed two of the split animals together and they get an offspring that is homozygous for the trait that it dies (which fits with the 25% of the eggs never hatching in your button quail mutation). Only one is ever known to have hatched on its own and that specimen only lived for a few days. Weird, huh?
