What are the different mutations of Goldenface? I know all of my "Yellowface" birds are actually Goldenface, so what would I get if I paired a GF to a GF?

 

What I'm asking is, are there two mutations of Gf like YF (ie, type 1 and 2) and is there a double factor version, making a white-faced bird who will have all GFbabies?

 

I think there must be a variation where the yellow is strictly on the face, and one where the yellow is spread through the body, as I have had birds of both types..whose yellow faces were truly golden, not the pale yellow of Yellowfaces.

 

Hi Jen

 

 

Read here. Has pics and explanations of ALL YF mutations.

There are only 3 forms of YF - YF1, YF2 and GF.

 

However RIP did comment that when you get combinations of these genes other things can happen so I assume if you have a DF YF1 (white face) that is also a DF GF, it might well remove all the yellow that would have been present had the GF genes be there on their own. It's when you get combinations of these genes that I start to lose my way. But maybe RIP can comment further.

 

As you will see on the above thread though the single factor GF is yellow spread on the body and the double factor GF has yellow restricted to the face...... please have a look.

Thanks for that. I read through it, and I just want to make sure: Assuming they are only Goldenface..

A SF GF paired to a SF GF will have 25% SF GF (yellow all through body), 25% DF GF (yellow restricted to face), and 50% normal white-faces. Right?

 

Though I have another question now. A Goldenface bird (whose yellow was restricted to the face, except for a few feathers on her front) was mated to a normal male. Thier one baby had been fostered (so there could maybe be a mixup) but it was a white-faced baby. The female, according to the explanation, would have to be a DF GF..which would make all her offspring SF GF, yes? How could that work?

 

Also, I've never seen an actual Yellowface bird (not Goldenface) anywhere around here, except show birds..and that has been for years, I've never seen a YF bird in real life. So most likely none of my birds are composites, though of course it could happen, so I'll try and understand that if it ever happens that one of my supposed GF birds has some YF offspring...

A SF GF paired to another SF GF would give:

 

25% chance DF GF

50% chance SF GF

25% chance normal blue.

 

The other thing I guess you have to remember is that in birds (as with all animals) there is natural variation in strength and intensity of colouring due to heaps of different reasons. So my first thought would be to remate the birds to see if you get the same result and if you do then I would be thinking that you have a SF GF with more restriction of yellow production than normal (or a body colour/feather structure that hides suffusion well on the body colour (or both)).

 

Again when RIP gets herself out of bed maybe she can comment :rofl:

I was wondering if you could put up pictures of these birds, so we could see the intensity for ourselves? Plus RIP is good at distinguishing the different factors.
