I believe that you speak of a yellowfaced Blue type 1. This is a dominant variety and so you need to start with one or at least a yellowfaced Green split to blue. Not all green birds are yellowfaced even though they have a yellowface. (confused yet?). Pair the Yellowface Blue to blue or grey and you\'ll get a percentage of Yellowface Blue, Yellowfaced Grey and normal blues and greys, possibly even a green. If you pair a yellowface Green split blue to a blue you will get a percentage of Yellowfaced Blues from it.

He he or you could just cheat like i would and pair a yf to a normal blue -_- who needs green Daz ;) that's for people more skilled at all this, like you :hap:

i breed 1 yellow-faced to 1 white-faced and you shold theoretically get 50% yf and 50% white faced

Yes Yellowface is a dominant variety.

Hi there,

 

I refer you to this website for information on yellowface budgerigar genetics:

 

http://birdhobbyist.com/parrotcolour/peter/yface01.html

It is very interesting and enlightening if you take time to understand it.

 

The yellowfaced gene is semi-dominant, like the spangle gene, where single and double factors look different. There is more than one type of gene that creates a yellowface, more than one type of yellow psittacine pigment, and more than one gene that can make a budgie blue (by stopping or reducing synthesis of yellow psittacine pigment). This makes for a plethora of interesting combinations if you were to specialise in breeding yellowfaces only, and yellowfaces in different variety markings too.

 

A visual yellowface blue appears when a blue budgie has a yellowface gene in single factor, that is when it is inherited on one chromosome from one of the parents only - I abbreviate YFblue(sf).

(Can also be in a grey budgie as a yellowface grey).

 

If a yellowface gene is present in double factor, that is when it is inherited on both chromosomes, one from each parent - I abbreviate YFblue(df), this budgie will LOOK LIKE A NORMAL BLUE with a WHITE FACE, but BREEDS ALL YELLOWFACES - these are very useful stock birds to have for yellowface breeding.

 

Start with a bird that is visually the yellowfaced blue bird that you would like to breed, genetically it will be a YFblue(sf).

 

These are two types of pairings that I do to breed numbers of yellowface blues:

 

1. YFblue(sf) to Normal blue -> 50% YFblue(sf) & 50% normal blue

 

2. YFblue(sf) to YFblue(sf) -> 50% YFblue(sf) & 25% normal blue & 25% YFblue(df)

 

The yellowface blue (double factor) will look like a normal blue with a white face, (and will be difficult to distinguish from the normal blues), but will produce all yellowfaces if paired back to a normal blue:

 

3. YFblue(df) to normal blue -> 100% yellowface blue (theoretically - as always exceptions are possible)

 

But you will only know the difference by test mating your YFblue(df) bird to a normal blue.

 

Once you know by test mating that it is a YFblue(df) bird (that is, when it produces ALL yellowfaces when paired with a normal blue), you can create the following pairing to produce visual yellowfaces and more df stock birds.

 

4. YFblue(df) to YFblue(sf) -> 50% YFblue(df), 50% YFblue(sf)

 

(Note: Don't do pairing 4 before pairing 3, otherwise you won't know if your normal looking blue bird is actually a double factor yellowface or not.)

 

The yellowface blue (double factor) birds are very useful stock birds for breeding yellowfaces, but they look like normal blue birds. The yellowface blue (single factor) birds are the visual yellowfaces that you like.

 

You can also do all the above in yellow face grey, but you might get a few yellowface blues popping out here and there because grey is dominant to blue, so a grey bird can be split for blue.

Now, you can breed your yellowface blues back into green budgies, but you will have difficulty distinguishing which green budgies carry the yellowface gene, so I don't recommend doing this until you get your head around the genetics. And, yes, from a pairing of a yellowface blue to a green budgie, you can get normal greens split for blue, normal blues, yellowface blues, and greens that look normal but carry the yellowface gene and are split for blue.

 

Right, that should be clear as mud.

Have fun, experiment. Discover for yourself that genetics is full of surprises.

 

Cheers.
