Default Genetics Question

If an albino female is mated to a blue base yellow face II dominant pied male, can you get green base babies?

I am starting to wonder about one of their babies that I have because he is a lime green color and I have yet to see blue. He is a yellow face II baby. So I assumed blue + yellow = green but like I mentioned, I am worried because I see no blue so far. He is not yet 3 weeks old.

Another question I have is with the same above parents, can you get a yellow face type I? The yellow on the face only if the dad had yellow on face and body? I assume the mother is a carrier?

Im a bit confused about your question. If the dad is a YF2 dominant pied blue male, he should be a seafoam green colour. Unless he is a double factor dominant pied in which case he would have almost no colouration and appear almost like a creamino (visually at least).

So if he is a double factor dominant pied, and the female albino is masking no dominant pied than ALL your chicks will be single factor dominant pied which would likely produce a band of clear (white) feathering across the mid belly or lower chest and the wings/flight feathers, with the rest of the colour appearing blue (upper chest, back, rump etc)

If a chick was also to inherit YF2 from dad, then the clear band and flights etc would appear yellow, and the rest of the bird would appear seafoam green as you say - there would be no blue due to the mix of blue + yellow = green.

I guess im confused as your post seemed to answer your question? Could you be a bit more specific, or perhaps i answered your question?

p.s unless the father is split for albino, all your male chicks will be split for albino and none of your females will possess the albino gene.

Excellent answer I was going to answer this morning BUT i am no good at genetics lol


But I did want to add / Ask (maybe i'm wrong)

but there are no "green based budgies" there are only white and Yellow Based

I do know with the Yellow Face Type 2's the body color normally doesn't change until maturity So when they're young they dont' look "sea foam Green" they look sky blue

You can't get a green (yellow) based budgie from mating an albino to a type 2 yellow face but you may get a yellow face bird that looks greenish. The yellow would be a lighter shade than the yellow on a normal green and the body colour would be an indistinct greenish shade of blue.

Your second question about the yellow face is possible. If the mother has a white face but she is a double factor type 1 yellow face all her chicks would be type 1 yellow face but as the dad is type 2 yellow face half of the chicks would also be type 2 yellow face. The chicks that had both mutations of yellow face would just look like type 2s. If this is the case with your pair then there would be no white face chicks. A lot of type 2 yellow face birds look like type 1 until they moult

What if both parents are White faces - normal mutations other then the splits the father has

what would cause all the babies to have Yellow Faces?

Exactly what i mean. Chances are your two 'white faces' where a white face and a double factor yellow face type 1. Double factor yellow faces are white (go figure!) so that means all your chicks would have been single factor yellowface type 1 as you said (visual yellowfaces).

Then pairing two single factor yellow faces would give you 50% single factor yellow face, 25% double factor yellow face and 25% white face. Aaaah, lets not even talk about YF type 2 or goldenface *dies*
