Equivalent mutation in ringnecks
Can experts please share what is the equivalent mutation in ringnecks or even in the budgerigar for DYC (Dominant Yellow Cheek) which is found in the cockatiels ? It inherits co-dominantly and changes the cheek patch to yellow which is otherwise orange red in the wild type cockatiels . Thanks

Hi Sherjil,
I know nothing about cockatiels but a change of the cheek patch from orange-red to yellow inheriting as co-dominant points to a parblue mutation.

Hi Recio;
The parblue equivalent are the PF pastel face and CF cream face which are allel of the WF white face (blue mutation is called WF in cockatiels) ; however the DYC inherits co-dominantly towards the normal grey which is the wild type.

Hi Sherjil,
A parblue mutation is a mutation partially removing psittacins. The DYC is partially removing cheek psittacins so that red psittacins can not be further produced and there are only yellow psittacins (data points to the production of red psittacins from yellow psittacins).
From your post I deduce that the DYC is not allelic with pastel face, the cream face or the white face (blue equivalent).
My conclusion is that the DYC is a parblue mutation of a different gene that the DF-CF-WF alleles. There would be at least 2 different genes regulating the cheek psittacins. Maybe one of the genes acts on the synthesis of the yellow psittacins and the other on the enzymatic transformation of yellow psittacins to red psittacins. In this latter possibility we will never get the blue counterpart, since the yellow psittacins would always be produced. So ... 2 possible parblues (2 genes) but only one possible blue. Just an idea.

Hi Sherjil,
what you describe reminds me a lot about the orange face (autosomal recessive) and even more the pale face (incomplete dominant) mutations in the agapornis roseicollis (peach/rose faced lovebird). These are typically considered as species specific mutations, so I don't think a ringneck equivalent exists, or perhaps more accurately have been identified/reported. Of course, species specific status will be lost if the same action is found in other species, possibly like this example. Both the above mutations also influence the psittacin spots in the tail feathers of the rosy.
I'm not to clued up on cockatiel mutations, so is the phenotype you describe for SF or DF DYC? And what does the other one look like?

Re: Equivalent mutation in ringnecks
Thanks for your reply Recio & Johan 
DYC is one of the rarest and newst mutation found in cockatiels. It was discovered in the US in the 90s. Here is a good link from a US breeder which explains some nice details of this mutation : http://www.justcockatiels.net/dominant- ... cheek.html
According to her there are no such SF and DF phenotype (just like the grey mutation).
Recio; Yes the DYC is not allelic to WF , PF & CF. And there is no such blue counter part or allele known for DYC yet. Interestingly pairing DYC with WF will bring back a blurry yellowish orange cheek patch but not the proper orange-red.Recio wrote: From your post I deduce that the DYC is not allelic with pastel face, the cream face or the white face (blue equivalent).

Johan; I dont know much details about lovebirds but the mutation named "pale face" might be of interest. How does this mutation act on psittacin ? do we have SF & DF pale face phenotypes ? Can you give more examples of psittacin effecting mutations that inherit dominantly ?Johan S wrote: what you describe reminds me a lot about the orange face (autosomal recessive) and even more the pale face (incomplete dominant) mutations in the agapornis roseicollis (peach/rose faced lovebird).
