Can a green be a yf2? I've heard that yes they can, but of course because they already have a yellow face, you can't tell until you breed them..If they can be yf, then what about double factor yf? Doesn't that make (in blues) their face white, though if you breed them you get yf's? What would that do to greens?

 

Thanks.

well there has never been a white faced green, so if it could hold the gene and it was a DF then it would still be yellow faced...

Green, Yellowface and Blue are alleles of the same gene. They can only carry two of these genes at any one time. Only dealing with single factor here. Each gene is separated with a hyphen followed by the visual result.

 

Green-Green = Visually Green

 

Green-Blue = Visually Green. Carries Blue gene

 

Green-Yellowface = Visually Green. Carries Yellowface gene

 

Yellowface-Blue = Visually Yellowface. Carries Blue gene

 

Blue-Blue = Visually Blue

thats a bit confussing but then im not to good at things with out pics yes you can have a yellow face green their face is a darker yellow usually only golden face you can tell with im not into green birds much so i cant really tell you more than that usually yf green birds are yf2 or golden face sky blues i could be wrong but one they are adult they just look green for some reason the wrong picture keeps coming up thats better sorry although the first bird will turn dark green

A Green bird that is carrying Yellowface will not show a brighter yellowface.

 

The yellow pigment on the Green bird is the pigment in its full intensity.

 

On a Yellowface bird the pigment is reduced by varying degrees depending on which mutation it is.

 

Remember that in all budgies there are verying degrees of brightness of the yellow and black pigments. This is due to "natural variation". The structure of the feather shows variation also and this in turn will ensure the green birds vary in colour. Line up a bunch of Light Greens and if you look very carefully you will see that no two indiviuals are exactly alike.

really rip i belive you

but i read that the yellowface on a green bird shows up as a darker yellow but as i read it was not sure if true or not

alot of books give out alot of wrong infomation why i joined you guys

 

can you explain to me please rip why some yf1 birds have yellow through their wings or are these golden face ones can anybody post pics of yf2 buby then as adult

yf1 buby then adult

goldenface

same as above and

gf1

gf2

as i have always wondered if i have a mix or just yf2 birds

Okay then, so yf greens are possible..you just can't tell unless you breed them..so if it's a double factor yf, then it's still got a yellow face? (on a green bird, not a blue)

I actually have no idea about the YF genetics, but I always assumed that YF is a blue variation, not a green, so a green might be carrying it if they're split for blue, but it doesn't "show" up on them in the same way that the blue they are carrying doesn't show up (even though green has both yellow and blue pigment- which is why it doesn't need to "show up"-- it already has a yellow face; it already has blue in its feathers, regardless). I'm probably wrong though and this probably made no sense :yes:

Yeah that was pretty much what I thought..about how it shows up on them..I didn't even think that they might have to be split for blue for them to carry the yf..I suppose whether that's true or not would have to do with what gene they carried the yf on or whatever..I don't know much of genetics lol. I hope that made sense.

Yes I agree-- I don't know whether they need to carry blue to carry yellowface. My guess is not necessarily, but the yellowface will never manifest until some offspring down the line is eventually blue anyway. It would be interesting to know how it works.

Well seems like ya missed the point. I will try to put it as simplistic as I can.

 

Original bird is Green. Green feather = Melanin, yellow pigment, structure

 

This gene mutates and you get a Blue bird. Blue feather= Melanin, NO yellow pigment, structure

 

This gene mutates again to Yellowface. Blue feather = Melanin, SOME yellow pigmant, structure

 

This green gene has mutated 4 times and produced the following: Blue; Goldenface; Yellowface M2, Yellowface M1. Each if available in single or double factor.

 

A bird can only carry two genes.

A Green that carries blue cannot be yellowface.

A Green that carries Yellowface cannot carry Blue.

A Green cannot be a double factor Yellowface and split for Blue at the same time.

 

I too have heard many people say that a Green bird who is also Goldenface will show a brighter face. No one has yet put a bird in front of me to prove that. Any birds that I seen that were questionable have turned out to be Light Green with a stronger yellow pigment with no YF in background. Beware the myths and ledgends. They just don't go away.

 

All life on this planet exists with VARIATION on the basic model. Without it life would not have evolved.

 

I was going my photos last night to see what budgie ones I had left. I came across a photo sent to me by Pantcho Tomas in NSW. It is of a composite Yellowface and Goldenface. I will post it once I have it scanned.

If getting a df yf green won't work, (which it probably won't seeing as no one has bred a white faced green yet) then why? I'm just wondering as how this mutation (yellowface) works, and why a df yf wouldn't be a white face in a green?

Edit: sorry I didnt see the above post

So if a budgie can't be yf and split for blue at the same time..what would you get if you bred a yf blue to a yf green? Would you get some yf greens (that aren't split for blue) and some greens that are split for blue?

I'm kinda confused now how you would get a yf green...

Thanks RIP - it's starting to make sense now :yes:

Let's see if I have it right yet....

 

It can only have two of the alleles... and we already know that to be visibly green, it must have green as one of them.

 

So it's either going to be:

 

Green-Green

Green-Blue

Green-Yellowface

Ohh I think I get it now..so to get a yf green, one of the parents has to be a yf, of course..but whether you have 1 blue and 1 green or both greens doesn't matter? I'd think having both parents be yf, and both greens, would make a lot higher percentage of the babies being yf greens? Because if there was one green and one blue, all of the babies would be split for blue and therefore not yf?

But how on earth will you know if a green is also yellowface, if they are split blue then they aren't yf..how would you breed them to find out??

Edited January 2, 200916 yr by Jen144

It doesn't matter what combination its parents are, it will only get one allele from both of them. If it got the YF from both of them, it would be a YF, not a green. So it makes no difference to be a Green-Yellowface that has parents that are both Green-Yellowface, or if it has a Green-Green parent and a yellowface parent.

Guys I think your getting it.

 

If you have a Green bird who you think is also a Yellowface then simply mate it to a Blue bird (3rd pairing below).

 

Green (2 green genes) X Blue (2 blue genes) = 100 % Green/blue (1 green gene and 1 blue gene)

 

Green/blue (1 green gene and 1 blue gene) X Blue (2 blue genes) = 50% Green/blue (1 green gene and 1 blue gene) and 50% Blue (2 blue genes)

 

Green/Yellowface (1 green gene and 1 YF gene) X Blue (2 blue genes) = 50%Green/blue (1 green gene and 1 blue gene) and 50% Yellowface (1 YF gene and 1 blue gene)

Yep I do get it now (although only on this basic level- I do not get YF1 and YF2 genetics yet at all!)

 

Thanks for your patience in explaining it

Okay I get all of that...one thing I still don't know..is how to get a green yellowface in the first place? None of the pairings you listed tells how to breed a green yf..

Read these articles...again. And again...

 

Yellowface genetics, parblues are not simple.

There appear to be different alleles for the same genes and different genes that can make a bird blue resulting in quite a few permutations and combinations.

A bird can be green and carrying yellowface, the same way a green bird can be split for blue, only yellowface is dominant and it shows in the green bird as a richer yellow and blotchiness in the body colour that darkens with the first moult. Yes it does.

 

Trust me on this one, I breed them: out of a pairing of a green bird that is carrying yellowface2 to a blue bird, you can get greens, greens carrying yellowface, blues and yellowface blues, because there are at least two different genes (not merely alleles of the same gene) that can make a bird blue. There are different genes and alleles of those genes coding for yellow psittacin pigments too.

 

Out of a pairing of a yellowface blue to a green/blue, you can get greens, greens carrying yellowface, blues and yellowface blues.

 

If you pair two yellowfaces you can also get a double factor yellow-face2 blue that appears like a normal blue, but when paired to a normal blue, all it's offspring will be yellow-face (single factor).

 

I do not yet know whether it is possible for a green bird to be carrying two copies of a yellowface gene that prevent pigmentation in the head and still be green in the body colour without pigmentation in the head... (ie white-faced green) but I'm working on it, I just have to get the birds to co-operate with me!

 

Everything in nature has it's opposite. The counterbalance to the yellow-faced blue is the white-faced green. I believe it will come from breeding yellowfaces back to greens... eventually.

It would be a nice bird if it ever does appear. I can't picture it, but I guess no one could've pictured the other mutations we now have when they were first seen out in the wild.

Okay thanks. That answers all my questions..

dr nat cheers i needed all that info specilly how to get a one factor yf out of two type two yellow face and i will need to read it over and over again lol :yes: :hug:
