I have always thought they lay on the same allele but what I have learned today is very interesting. If anyone has any comments, additions or debates lets learn but I have learned that I have been giving wrong advice.

 

This is what I found out...

 

A Greywing can be split for dilute (this I never though was possible from what others have told me)

A Clearwing can be split for dilute

Greywing & Clearwing are co-dominant

 

Greywing and Clearwing are dominant over dilute

So example if you bred a Normal split to greywing and normal split to dilute budgie you would get 75% Normal 25% Greywing NO dilutes

Normal can be split for dilute OR greywing OR clearwing

A dilute can not be split at all because dilute is recessive to both of the genes above so a dilute budgie is dilute period no split.

 

So for example: If you bred a Greywing split to Dilute x Clearwing split to Dilute this would be the offspring possible %

25% Full-body-color greywing (remember the greywing and the clearwing combined create this combination because greywing and clearwing are co-dominant which means they don't dominante each other)

25% Greywing

25% Clearwing

25% Dilute

 

Pretty cool....

There is a reason why I am so confused about genetics... Its cos its to complicated... I never did get algebra and I probably won't ever understand genetics...

Hmmm I always thought that Dilute could be in a split form .... Interesting Elly ..Thanks for the read - Where did you read it ???

See Neat I was told it could be on say normal to dilute but not to greywing or clearwing
