Hi again everybody

Hope this time I will get an answer.

Does anybody know the phenotype of the following crossing overs:
1. Crossing over cinnamon-opaline
2. Crossing over ino-opaline
3. Crossing over pallid-opaline and palid-ino-opaline (males)
4. Triple crossing over cinnamon-opaline-ino (or pallid or pallid-ino for males)

If anyone can post a picture it will be great.

Hi Reico
Im not sure exactly what you want.
Example do you want to know what you will get with a cinnamon bird mated to a opaline etc?.
If so can you give me colours for each bird and specify males and females i should be able to give you exact results for outcome of young.
And when you say pallid-ino do you mean a pallidino as im sure you cant have a pallid split to ino.

Cheers

Here you can see a pallid-opaline crossover:

I dont like such birds. A true opaline bird looks much better then such mixed bird.

I just want to know the apearance (phenotype) of birds displaying these sex-linked mutations together, if possible in females and males, on green and blue series. Why? Because I wonder if interactions between genes placed in the same cromosome could altered the final expected apearance.

And when you say pallid-ino do you mean a pallidino as im sure you cant have a pallid split to ino.

Of course I mean pallidino. There are not ino splits pallid nor pallids splits ino, since pallid and ino are 2 alleles of the same gen, placed in the same locus.

I had to ask some of those things as here in Australia people have several names for the same birds.
Also we do not have alot of opalines here to my knowledge.
I only know of maybe 2 people that have them and are real opalines.
The picture parts for all these mutations i would not know where to start looking besides that one on Jays website .
I have birds similar to it but mine is what Jay calls a cinnamon pallid crossover ,looks very close to the same but genetically it is totally different bird.
If i come across any photos of opaline crossed birds i will list them up.
Cheers

Hi Madas

Thank you for the info. I agree these birds are not very beautiful but they can help in understanding genetics . I did not know if such crossing over would display a clair head (as pallids do) or a dark head (as opalines). By the way do you know if the dark head of opalines appear afther hatching, after first moulting or after reaching sexual maturity?

Since it seems that opaline acts throw a hormonal mechanism (MUTAVI) I was wondering what it would be the expresion of opaline in the clearhead (buttercup) or the clearhead-cleartail IRN, since those are also depending of hormonal status (they are only expressed at sexual maturity). Would they display a dark head, as opalines, till reaching sexual maturity and a clearhead afterwards?

Is there anybody with a picture of the triple crossing-over (cin-opa-ino/pallid)? .... it os becoming an obssesion.
