IRN Genetics?

[SparkkiSparkS]

As you may know, my new IRN is white and I was wondering if I could possibly figure out what color her parents were? All I know is her brother from the same flock was green/blue. ALSO I've heard that the white males wont get a ring and there will be no way to tell the sex with out DNA testing? I do believe the lady that said she was a female but still want to know if I should get the testing done at the vet or not..

That depends on the mutations involved.

If one sibling was green split blue, then you know that at least one parent was yellow based bird (i.e. yellow or green) split blue. The other parent was either visual or split blue.

Now, depending on genetics, either the father was split ino (lutino/albino) or both parents were. I don't know which mutation is more common in IRN's, but there is a sex-linked version and a recessive version.

Can you not ask what mutation her parents are?

They lady I got her from didn't know the parents. She bought both of them from an exotic petshop, and soon realized it might not be the best to have a brother and sister together. So will the ring still develop on white or albino males?

Oh and im not sure if he was green "split" blue, but he did have a good bit of blue feathers on him although mostly green.. I just want to know these things.

If he was a blue-green bird, this would indicate he's a par-blue mutations.... turquoise or aqua.

I don't know too much about IRN mutations, so a faint ring may develop, but being that there is no color there because it's been removed completely, well... it may not.

The lutinos develop a pink/white ring. Pink where the pink normally shows up, white where the black normally shows up.

Blues develop white/black rings. White where the pink normally shows up, black where the black normally shows up.

When you remove all color, you end up with white... so you'd basically be looking for a white ring on a white bird. Not easy to see...

Thanks Monica! He was a normal shade of green, but had a few random blue feathers. I found a pic of a white one with a nice black ring, but also found there is an albino mutation and a white one that is just a really lightened grey mutation. This is still new and confusing to me lol.

 

[MonicaMc]

The white ringneck with a black ring probably wasn't a true albino. Could have bee a very lite shade of grey or some other mutation. Gorgeous, no doubt!

Genetics is confusing! More so when you have two or more mutations that are the same (pied or ino for example) that have the same basic effects to the feathers, but are acquired in different ways (dominant, sex linked, recessive).

Is a white(albino) the result of mixing blue+lutino?

 

[MonicaMc]

Albino actually implies it is one mutation, but it is in fact two, in parrots, because there are two different kinds of pigments that control colors in parrots.

Albino is in fact a Blue Lutino, or Blue Ino to be a tad more correct. For simplicity, it's called albino.

Thanks again! Just when I got reptile genetics down, I have to start asking about parrot genes! LOL
