Single factor yellow/dilute yellow?

[Vertdemer]

Better pictures of the tail... My new ended finish molting guy and grandfather tail...
It's why I call them "Opaline"...like Opaline gem stone and all there rainbow colors...!!

Very beautiful and interesting coloring! How do you even go about getting the seagreen mutation?

I'm not sure to understand well the question(sorry, I'm currently french speaking... ).
If I understand well...I'll try to explain what I do to have bluer birds...
I have one hen who is maybe a Seagreen but I'm not sure... She's really bluer than normal green back and she's really dark too so I think when you have a bluer bird and you match it with an other "dark bird", maybe you can produce bluer or more intense colors for their siblings...
The father his the OH WB(lilac???) Double factor that I had put pictures at the start of this topic...intense colors too!

That sf red head male is a Beauty! I love the grey-blue neck ring and that tail...how unique!

Thank you very much Candace. Your post and website helped me out a lot. It all makes sense to me now and was all so easy to understand I really appreciate it.

Oops, then I am about to put a spanner in the works! SF Pastel Green is not the same as Dilute. It is actually unrelated:

- The Pastel gene is co-dominant and sex-linked. It causes dilution of any back colour be it Green, Blue or other variations.

- The Dilute gene is autosomal recessive.

What most call "dilute" here are SF Pastel Green or SFYellow, totally different from your dilute in australia. Which isa good reason not to use the made up American terms "dilute", "pastel" and "silver"

Hi Stephanie!
What say about European yellow is correct and it is good to give our birds the right label.
In your homepage you declare the inheritance of some other mutations.
Where does this information come from?
Is this your experience or did you read this in books.
Years ago some people in Germany wrote about the inheritance of mutations and nobody knows from whom the informations come from. For example two people told me recently that the pied mutation is dominant, but couldn't tell where the information come from!!!
Thanks Bernd

Notes:
A ‘lethal factor’ exists. Do not breed DF cocks with SF hens or you will lose chicks in the nest.

I've never found this to be true. I'm wondering what the supporting evidence is?
I never lost a single chick in the nest as a result of a DF cock x SF hen.

Hi Bernd

As per the heading of the page...
"Based on the 2005 guidelines and terminology suggested by A Guide to Gouldian Finches & Their Mutations, ABK Publications." The authors are Gouldian Finch experts from Australia.

Their recommendations are presented comprehensively but extremely confusingly in the book - but, once you dredge through and untangle it all, it becomes clear that they make very good sense. The genetics fit together properly all the way down the line. It's very thorough and precise.

Using casual labels for what a bird looks like, rather than the actual genetics which produce that appearance, causes compounding confusion. I find it much easier to stick to the formal classifications.

Nixty, I have heard others with your experience too. My suspicion is that the belief in a lethal factor might have arisen from early intensive breeding of this mutation - that is, losses due to classic in-breeding - or perhaps as a result of pairing the wrong head colours, before that was understood to produce major losses of offspring.

Because of your experience and others', I'm going to see about getting that sentence removed or modified.

Thank you

Sorry these took so long was having trouble uploading photos for the longest time

Lol pirate. Thats cute

my kids are just 6 and 4, when we brought the goulds home, they looked at our yellow male and said that he looks like a pirate because of the red "bandana" on his head lol! ;)
