GB a DF Recessive Pied is a visual Recessive Pied i.e. it carries two genes for Recessive Pied. The split could be considered a SF Recessive Pied.

 

Just my rant here. I don't know where it started, but using the term 'Clearflight' in regards to Australian Dominant Pieds is confusing. Clearflight is and has been used for a good many years, exisited within the name 'Continental Clearflight' which is an alternative name for the Dutch Pied. The orignal name for the Dutch Pied was 'Continental Clearflight' and was so named as it emerged on the Continent (Europe). You must remember back then England was the hub of budgerigar activity an as such a central point by which all subsqent mutation occurance was measured.

 

When talking about Australian Dominant Pieds names such as Flighted, Banded, Dominant come to mind.

 

Nubbly mentioned earlier that a bird could be a df Aussie Pied, df Dutch Pied and a df visual Danish i.e Recessive Pied all at once. What would a bird like this look like? Well based on current knowledge it would most likely be a Dark Eyed Clear that is masking (Phenotype not geneotype in sf or df form) Australian Dominant Pied. I have seen, albeit a few examples of Australian Dom Pied x Dutch Pied indiviuals I have yet to see the aforementioned composite of all three. If somebody wishes to prove that a certain example exisits they must also be able to show irrefutable evidence that the bird is indeed a mixture of pied types. Neville posted some comination pied types. I have looked at these pics and the evidence (pedigrees) supplied but as I look at things in a more indepth nature than most I find that the evidence is flawed. When a scientist proposes an experiment to prove or disprove a theory he/she sets out to make sure that the evidence must be plausible and above all must not be able to be pulled apart and eventually found to have holes in it. If this happens the evidence is flawed and so the results come into question.

 

 

When previously in the hobby I bred all the pied types. Dutch Pieds are extremely variable in their markings. Phoeobe's partner appears to be a Dutch Pied. Phoebe herself a Dominant Pied. Both appear to be single factor. Now the resulting offspring, in respect to pied types, can be.....Australian Dominant Pied; Dutch Pied; combination Australian and Dutch Pied types in a variance of markings. This marking variance is the result of reaction by alleles controlling the various mechanisms involved in creating and controlling the 'pied' pattern.

 

As for double factors. Well in Australian Dominant Pieds there is a tendency for a double factored individual to be pocess a greater 'pied' area than a single factored bird. This is also true in other lifeforms and in fact in some animals (horses is an example) lethal. In Dutch Pieds this tendency appears not to exist. The years I was breeding them I found great variability in 'pied' markings. Although the two pied types of Dutch (Lucistic) and the Danish (Anti-dimorphic) being different types when placed together form another invidual completely different from its parents.

 

I have included as couple of links. The Dutch Pieds are quite similar yet one is single factor, the other a double. The Mauve is the sire of the Olive.

The Australian Dominant picture serves to show that in this 'pied' type there are exceptions. He is NOT a double factor. His parents where a Dom Pied and a Normal. In fact he went on to breed Dom Pieds with less markings than himself.

 

single factor Dutch Pied

 

double factor Dutch Pied

 

single factor Australian Dominant Pied......look how pied out he is
