Hi Sherjil,

1) As the bird is visual cinnamon & it is kept in an outdoor aviary, is it possible that the dilution on the flights may be due to exposure to the sun ? If so then why this dilution is showing a specific pattern rather than giving a bleached effect of the exposed flight feather area ?
I agree. It seems unlike that the feathers pattern is due to sun bleaching.
2) The visual attributes shows that the hen is active and healthy, in fact the owner has paired it with a violet male & they are working the nest in this hot summer of Pak, can they really be stress marks ? For the sake of questioning lets suppose it carries SL D Edged then this makes that the father has ino on X1 & Cinnamon-SL D Edged (crossed over) combo on X2. With this genotype is it possible that SL D Edged is not visible on the flights due to crossing over with cinnamon plus effect of ino ? Anyone has a snap of a bird with similar genotype i.e. Hetrozygous Parblue split ino split cinnamon-SL D Edged ?
Good analysis & I agree completelly. The question is: could the addition of cinnamon (and/or) SL-ino play a role in the expression of dom Edge? Tienie should be able to answer this question much better than any of us.
3) Coming to the parblue does the indigo blue strictly has a "white" & not a "creamy white" neck ring ? What is the neck ring color of homozygous indigo birds ?
The parblue puzzle was discussed in the past. For me the markers to consider the 3 different morphotypes of patched parblues are as follows, from more to less psittacin expressed:
Turquoise morphotype: Black, red and white ring in homozygous (TurquoiseTurquoise) and heterozygous birds (TurquoiseBlue)
Indigo morphotype: Black, red (ligth red) and white ring in homozygous birds (IndigoIndigo). Black and white ring in heterozygous birds (IndigoBlue)
Saphire morphotype: Black and white ring in both Homozygous (SaphireSaphire) and heterozygous birds (SaphireBlue).
You can get intermediate morphotypes by combining different alleles (TurquoiseIndigo, IndigoSaphire, ...) adding further confusion to the expected results. We can "class" the male according to its phenotype and genotype, but it is harder for the females (no ring). The best way to be sure that we are looking to an homozygous parblue mutation is to breed back an heterozygous chick to his heterozygous parent, as you have done with your Indigos. This should be done with any parblue allele looking a little different in intensity or distribution of psittacins if we want to know for sure the homozygous expression and how many different patched parblue alleles exist. Till then the best we can do is to adscribe the expressed morphotype as if it was due to a unique parblue allele type. That is something like "if the heterozygous and the homozygous parblue both express the red ring then it is a Turquoise allele which is at work". Why could not be two or more different "Turquoise" alleles, expressing different degrees of psittacins, but all of them in a high amount, enough to produce the red ring?
