Ok, you have Molly's parents mixed up. Molly's mom is actually her dad and Mom is her dad! You have the sexes mixed up. Molly is a Pearl split to whiteface perhaps? Need to know more info about Molly's siblings or know the parents exact genes.

I don't think that female birds can't be split to anything because they always 'pass on' what they are -meaning, if the mother had a, say, a white face father but she came out as a wild phenotype, she will only pass on the wild coloring and not the white face. This is because they carry only one X chromosome so, even if one of her parents has a genetic mutation gene, unless the hen is visually showing the mutation, it cannot pass it on -or, at least, that's the way I understand it but color mutations are not something that interests me so I might be wrong.

Actually they can pass it on, while I was playing with the genetics calculator I found out they can.

interesting... i don't have the sexes mixed up the breeder told me when he sent me the photos although her dad does look like normal gray female!

Can you give me a link to this genetic 'calculator', Mikey?

Either your breeder mixed them up or he doesn't what what he's talking about! Trust me that's a normal grey female with a whiteface male.

Thanks! But I think you misunderstood. See this which I took from the link you gave me:

This means that females can have only one copy of a sex-linked mutation (the
mutation is carried on the X chromosome), and it follows that females cannot be
split to a sex-linked mutation. If a female does not visually possess the
sex-linked trait, she does not carry it at all.

My genetics with bird colours is actually horrific, my male budgie is "green" and my white budgie is an albino (yes an actual albino, not a colour mod to get white, etc.) So please excuse my horrific ignorance on the subject! (Gimmi human genetics any day, I'm good at that! xD)

So I just want to clarify; are you saying that females cannot have recessive colours that then pass on to their young? Because the colouring would have to be dominant in the female (for you to see it on the female) to pass on to it's young?

So females cannot pass on a recessive colouring?

Sorry, I'm not trying to be a pain, I'm just confused.

Maybe we could have a thread started on genetics of cockatiels/budgies? I think that might be interesting and some of us new folk to genetics might learn a lot

I know that's what it says, but what makes it confusing is one of my pairs, the babies they produce and after playing with the genetics calculator the only option is to have the mother split to Fallow in which it carries out in the offspring exactly the colors I have had from the pair. I have tried the color on the male in carrying it in X and also split, all the combination came out incorrect.

Ahhh, yes, but that's because fallow is a recessive and not sex-linked but pearl and cinnamon (the bird in question) are both sex-linked.
