The last 2 things on my bucket list

There are 2 things left on my bucket list. I still hope to find the answers on these questions,  before retiring in aviculture, but I need your help in this

  1. What about *Dominant yellow* Agapornis fischeri ?

Here we are very close to the answer but I need more breeding results. If you have these *dominant yellow* Agapornis fischeri in your collection please send us the breeding outcomes. Interesting to know is what the outcome is when we combine the *misty* phenotypes that are born out the combinations of *dominant yellow* with normal greens.


  1. What is the exact phenotype of a homozygote turquoise Agapornis fischeri?

This is a difficult question, especially because we have different opinions. One South African breeder claims that a homozygote turquoise looks as a normal blue. He refers to the Bergman theory’ and the test mating with its birds. Two American and one German breeder claim that a homozygote never shows a blue phenotype, but looks as a normal turquoise. Only the German breeder has send us breeding results from the last two years.

Basic problem in this is that nobody is sure about the complete background / pedigree of the birds. So it is not easy to find a clear answer on this.

For a good order: it is not a matter of he or she is telling the truth or not. I am long enough working on colour mutations in birds to realise that 1+1 is not always 2. The time that we are only focussing on genes and alleles is already long gone. Keep in mind, it is not the first time that identical genes give different phenotypes. Indeed, welcome into the world of epigenetics.

If you think you can help us, please contact research@ogvzw.org

    Wel ik kan u met zekerheid stellen dat een DF turquoise, of een homozygote turquoise zoals jullie het noemen, niet blauw is. Ze zijn gewoon turquoise gekleurd. Na meer dan drie jaar met ze te fokken ben ik hierover zeker.
