FAQ: Combinations of alleles of the same gene

FAQ: Combinations of alleles of the same gene are indicated by writing the mutant names one after the other, for example PastelIno. A capital is used to indicate the start of each mutants name.

But how do we write the name of a combination with epistatic genes?

Well here we have an  easy answer: exactly the same as we write alleles of the same gene! The mutant (gene) names one after the other. Why? It are also two (different) alleles that are creating a (non wild type) phenotype.

Cursus 2020

NOG ENKELE PLAATSEN BESCHIKBAAR – NOG ENKELE PLAATSEN BESCHIKBAAR

CURSUS AGAPORNIDEN 2020

in 2020 organiseert Ornitho-Genetics VZW voor de 10de en laatste keer, een cursus gespreid over 5 dagen.

Deze cursusreeks gaat door in Aalst, in de verkoopzaal van de BVA Masters (Sint Paulus Complex, Botermelkstraat 63c, 9300 Aalst – België)
op:
zaterdag 29 februari,
zaterdag  14 maart,
zaterdag 28 maart,
zaterdag 18 april en
zaterdag  2 mei,

telkens van 9 tot +/- 16u.

Dit is de ideale kans om uw kennis uitgebreid bij te spijkeren aan de hand van de nieuwste inzichten in avicultuur. Het merendeel van de materie over kleurmutaties en genetica is van toepassing op ALLE parkietensoorten en gebaseerd op internationale afspraken / richtlijnen.

U vindt alle info over deze cursus op onze website:

https://www.ornitho-genetics.info/?page_id=15224

Inschrijven kan tot 10 februari 2020 of tot alle plaatsen volzet zijn.

Aansluitend aan deze cursus organiseert BVA-International ook nog een cursus voor kandidaat keurmeesters.

Standaardeisen Agapornis fischeri ge-updated

De standaardeisen van Agapornis fischeri zijn uitgebreid met een tweede deel dat enkel de combinaties met opaline bevat. Verder werden in deel 1 nog een paar mutanten toegevoegd.

Agapornis fischeri blue2

The last months we received several reports from breeders who bred blue2 Agapornis fischeri which develop a yellow / pinkish forehead. We suspect that this (as I mentioned in my article about blue and blue2), can confirm our thesis that blue2 types probably still have the possibility to produce (a limited amount of) psittacin.
The link between * sapphire * and blue2 becomes also more likely. Hopefully we will be able to prove or counterprove this theory in the future by DNA analyses.

zebra finches [Taeniopygia guttata]

To conduct an experiment with zebra finches [Taeniopygia guttata] in captivity, we are looking for  zebra finches that are almost completely orange, almost completely black or almost completely white. If possible from breeders in Spain or Portugal.

Who can help?

Can parrots synthesize pheomelanine in feathers?

Can parrots synthesize pheomelanine in feathers? That is a point of discussion in aviculture for a long time.

We have not heard of any scientific study that confirms the presence of pheomelanin in the feathers of parrots. So it was still doubtful for some breeders.

In MUTAVI, we examined in the past several mutations in Psittaciformes by cross sections and never found visual pheomelanine in the feathers, but it is always possible that there are small pigments that could not be detect under the microscope.

The best way to investigate this is by Raman spectroscopy. Raman spectroscopy is commonly used in chemistry to provide a structural fingerprint by which molecules can be identified. So a perfect method to identify pheomelanin in feathers since it can detect / analyse the smallest pigments in feathers. We could not do this test, but we found a scientist who was willing to help us.

  • Daniel Nuijten (Nature preservation – Belgium)
  • Bert Van Gils (Chairman BVP Belgian Parrot Society – Master of Bioscience Engineering – Belgium)
  • Nico Rosseel (Aviculturist – Belgium)
  • Jef Kenis (Avicultural judge – Aviculturist – Belgium)
  • Eric Gennissen (Aviculturist – The Netherlands)
  • OFM Heinz Schnitker (Taxonomist – Germany)
  • Glenn Ooms (Editor BVA-International – Belgium)

 

selected 30 species / sub species (from the three super families in Psittaciformes: Psittacoidea, Cacatuoidea, and Strigopoidea) and a few colourmutations in which we have feathers with colours that are POSSIBLE candidates to be produced by pheomelanin (dull orange or chestnut).  All these feathers are analysed now by Raman spectroscopy and there is NO SIGNAL OF PHEOMELANIN IN ANY SPECIES.

We hope to publish these results in detail in a scientific journal. We will keep you informed.

Thanks to all who provided us feathers of these species and our sponsor who helped us to pay this research

 

 

‘Red’ Agapornis fischeri

Benjamin aka Joven of Aby Aviary from the Philippines and the South-African breeder Willie Matthews, reported success ful breeding records with ‘red’ Agapornis fischeri.

It looks like these red phenotypes have an autosomal recessive inheritance. Willie Matthews confirmed that this bloodline is NOT related to the ‘red’ birds that are born out of the fallow bloodlines. The birds are complettely orange red and are in very good health. Willie already has severall red youngsters.

Who can help?

We are looking for feathers of GREY Forpus coelestis. If possible tail feathers. Who can help?

Thanks in advance.

Opleiding keurmeesters BVA-International in 2020

Vandaag bericht gekregen van Frank Buys, coördinator BVA-International judges, dat er in 2020, aansluitend aan de theoretische cursus agaporniden (https://www.ornitho-genetics.info/?page_id=15224), een opleiding voor BVA-International keurmeester gestart wordt. Deze opleiding duurt twee jaar. Deelnemers aan de cursus die op alle modules meer dan 70% behalen kunnen zich hiervoor kandidaat stellen.

Let op: elke keurmeestersvergunning van BVA-International wordt jaarlijks door het TC vernieuwd. Wanneer de betrokken kandidaat, na het slagen, afwezig blijft op de bijscholingscursussen of geen agaporniden meer kweekt, vervalt het mandaat onmiddellijk. Zo zijn de BVA-International keurmeesters steeds verplicht om alles op de voet te blijven volgen en vermijden we dat ze ‘na het behalen van hun titel’ alle motivatie laten varen en zo achterop geraken.
BVA-International keurmeesters dienen er in eerste plaats te zijn voor de leden, de kwekers van agaporniden en niet voor hun eigen belang.
