blue dilute julieinWA followup

[fincher]

very nice birds julian glad to see another WA breeder of mutations in gouldians in the blues and so on

Yes calling a sf pastel cock dilute is incorrect as we can see now by the correct recessive dilute
I always could never understand why James always corrected me when I used to call the sf pastel green a dilute !
now I know why.
The visual difference is not easy but the dilute is a more pale lime green than the sf pastel green,,
also it can be white breast and male or female which the sf pastel g cant.
This is why its best not to put any yellow ( pastel green ) in the breeding.

Flavio
wow you have been breeding a long time then !
Do you have any photos of your white breast dilute ?
strange they drop dead after moulting but then this is what I have heard about the blues from most who keep them..
so the problem may not lie in your dilute it may be the line of blue
my blue dilutes just come out of two green backs and they have almost completed their moult
so hopefully they will be ok ... my two blues also have fully completed their moult .. they were fast to moult and
appear very active and healthy to date.. but this is my first lot of blues so I have to wait and see.

I am going to breed my blues and blue dilute hopefully all going well this season but to greenback wb or pb to try and
keep the line strong.
The same with the Dilutes they will be bred to wb greenback.

Great reading Julie Thanks for sharing the pics, they look great.
I still call sf yb dilutes as well, "ressesive dilute" term to differentiate between mutations, everyone else is getting too picky

[julieinWA]

yeah macstaa most people do call the sf pb dilutes , mostly because I guess they are like me and
others and had never known of the original recessive dilute .

Hi Julie,
Congrats, they are very striking birds you have there. Lets hope they stay strong and healthy and produce plenty of splits for you this season.

Great pics and reading...thanks JulieinWA....I was interested in one of your early posts (reply to Flavio) that you mentioned the Dilute Blue's produced have all been males....this is interesting given that both these mutations are recessive....does the combination of the blue and aussie dilute create a sex linked strain....seems odd but maybe more breeding results will show if this is the case or not....probably a question for the likes of JulieinWA, Flavio, Tino or Garyh (or any other breeders working with these birds that I have not mentioned)....either way you should all be commended for your hard work and patience you are putting into these birds.....the Dilute Blue seems to be (today) at the same stage the Blues were 10 years ago......they had a reputation of being weak, however with hard work and patience they can be strong breeders given the right care.....cheers, Paul

It does read as if it may be that the blue and dilute genes can only combine through a sex linked gene. But if Flavio has been breeding these for some time he may be able to comment on this. Assuming that these are the same mutation. And not a different but very similar mutation. Which though not neccessarily so is possible.

thanks ... yes I am really hoping they will do well given they are from green parents and grandparents
I may have a chance of a stronger line ... fingers crossed !


gouldianpaul
yes seems it may produce a sex linked mutation but will know more once I hopefully get to breed some again.
the parents of these blue dilute are just going to nest again so will be interesting to see what comes out
again.

Hi Julie,
interesting to hear the Dilute Blue may be a sex linked strain...all the best with these birds for 2012

Even if you have a new mutation, the all males is a coincidence. Dilute is autosomal recessive and blue is autosomal recessive. Each is separately inherited so you could get normals, blues, dilutes and blue dilutes from a green pair split for blue and split for dilute.

Furthermore, it would be impossible to get a mutation limited to males in birds. If the gene is on the W chromosome then a male bird can be pure dominant (as a red headed bird would be if pure), split (if it is recessive like black head), "halfer" if gene is co-dominant (as in a SF Euro Yellow) or pure recessive (again as in black head)/ A male bird has two Ws so no option allows for males only. A femael cannot be split or halfer, it is either the recessive or dominant form. On the other hand if the gene was on the Z chromosome then it would be possible to get females only. However genes only the sex determinate chromosome that affect things other than sex are very rare.
