"Biscuit" Yellow RFPF

[Joseph]

Bill,Craig and all members,
Thanks for your information and guidance. I'm hoping all goes well with this mutation of parrot finch. We will see how we go.
Thanks to all
Joe

I am going with sex-linked too. I have mentioned this too Joseph too and I have my fingers and toes crossed that he breeds more and get these birds going. Couldn't have happened to a nicer bloke than Joseph.

Just being 'devil's advocate' again . .

I am thinking S-L-R as well because of the seagreen . . . but, in Redbrows, Crimsons, Diamonds, Saints, where the red is replaced by yellow the inheritance mode is A-R

The bird in question, particularly in Tintola's first pic looks like it could be a cock

Obviously the first step is DNA sexing

I have to agree Arthur re autosomal recessive for the yellow but i can't help thinking that the seagreen has something to do with it as with the change of colour with the seagreen mutation to that horrible colour of the red.
I'm playing around with a yellowish looking crimson at the moment so don't have the stuffing around of a SL mutation. Craig

I actually think it looks more of a blue or par-blue type mutation with the yellowing of the red areas just the side-effect. To me the body colour has a distinct bluish look about it. If so, this would also be more likely to be autosomal. Consider as a possible similar case the phases of the blue gene in the scarlet-chested neophema ie. sea-green, par-blue & white-fronted blue.
The other possibility just to further complicate matters is a double-factor sea-green (more likely sex-linked with an extra degree of difficulty thrown in).
So much to learn - all part of the excitement of a different mutation.

I agree. Would be well worth the $10 to be sure. If it is a cock then that rules out sex-linked which would greatly simplify matters.

I think would be a good idea for me to D N A test my parrot finch

[finchbreeder]

DNA test is a good idea. And keep the normal looking siblings. Because obviously no one knows what this mutation is or what its mode of inheritance is.
And so it is best to assume, at this stage, that they will be breeding assets. Good luck in establishing this lovely little gem.

Joseph, you will have to shift of all your other finch species and devote all of your aviaries to this mutation . . too important to lose

And as $Bill says you have won lotto (so to speak)

I am sure that you have plenty of expert advisers in your circle who will assist, and a lot of well-wishers on this forum

Don't be overawed . . and . . Go for your life

Hi Arthur
Yes got my Hands full for sure.
I'm going to have to redo my set up to suit this biscuit parrot Finch. But in the long run I think it's going to be a good thing.
