This is Caesar - a sky blue cock

 

 

This is his yet-to-be named daughter, who is an albino hen

 

 

The understanding of the Ino gene is that it is sex linked, so if there is only one INO gene present, the male bird will present normally, whilst the female will present as an INO.

 

I always thought that for the Cock bird to carry the INO gene, one of his parents had to of been an albino.

 

Caesar's parents are:

 

A grey cock

 

and a grey spangle hen (sorry no picture)

 

The breeder of Caesar, a very prominent INO breeder who has won multiple times at the Nationals, is going back and rechecking his records. This breeder has also put Caesar's father down to breed with an Albino, in case the Albino gene is hidden in there somewhere.

 

Now, orginally all mutations and genes were hidden in there somewhere. We know that there is a recessive grey gene. Is is possible that the INO gene could somehow also be a recessive hidden gene, or that there is a slight mutation of the INO gene to allow this? Or is it possible that a father that is split to INO could pass along this split to his son, with it never being realised until later generations?

 

I would be interested to hear your thoughts on this.

Splits can pass on to splits and keep it going without the gene even been shown... a birds great great great great great grandfather could have been split ino and his great great great great grandson could be split without it of ever shown in the previous generations

i agree with libby...the grandfather of the albino must be split ino, passing it on to the father of the ino so that he is split ino, and know this bub has turned out to be white...i would call her snowball or something like that... Kaz usually has the good names

Kaz gets good names from me -

 

There is no history of INO's in this line of birds dating back to 2003.

 

I will be interested to see if Caesar's dad sires any INO's with his new pairing to an albino hen.

okay, the INO gene is sex linked. Only the cock birds can be split INO. Hens are either INO or Normals.

 

If you put a split INO cock bird to a Normal hen you will get 50% split INO and Normal cock chicks and 50% INO and Normal hen chicks.

 

So it is quite possible that Caesar's Dad was a Grey SPLIT INO!

 

INO's can mask other domiinant varieties, I have an albino hen who unless paired with an INO chucks Spangle chicks.

oh okay what names have you got for kaz to tell us????

If you put Caesar, who we have established is split INO to an INO hen you will get 50% INO and split INO cock chicks and 50% INO and normal hen chicks.

Yep grey bird is split ino. Caesar is also split ino. Ino can tick along in the cock line for a number of generations especially if you only get a couple of chicks each time and they are boys...... then out pops those ino hens later on down the track. Same happens with lacewings - which is why I now have YF white lacewings from a cobalt cock that I was not really aware was carrying lacewing to a nice YF hen. When I checked back his grand father was definietly split lacewing.

There has been no inos pop out of this line in 6 years. The breeder has now put Caesars father down to breed to a good albino hen

A good friend of mine had a cinnamon hen pop up in his line of normals he had been keeping 'pure' for eight years. He has only ever paired that line with his own normals and was completely surprised by the cinnamon showing up as he has no idea where it came from or how long it had been passed down.

This is a bit like that surprise greywing popping up in Omelettes first clutch this season.

i agree with all this

however i have a book called breeding budgerigars by cessa feyerabend and dr matthew m. vriends

and theirs a bit on inos that says

 

some albinos have been reported

 

that are not sex linked

 

personally i belive its just as nobody knew the true family inheritance from early generations

they are saying these none sex linked albinos can be showen at shows under clear fellow whites

 

it also states that breeding a white fellow cock with a albino hen

all the young will be black eyed normal coloured young

as the albino sl gene the gene for red eye and feathers with out pigment

are situated in a sex chromosme ,while in the white fellow they are in the normal chromosomes

the gene responsible for the red eyes and lack of pigmentation in feathers will combine with the normal gene and therefore will produce normally coloured young

but we all know this

 

my point being

that the gene must be in the fathers history some where he has to be / albino as does his father and his other family members down the line on the males side if their has been no albino hens in this line for years

 

if you breed birds with say three sex linkages

not all the young come out with both sex linkage they divide, so say you breed

 

cinnamon hen with a albino /lacewing cock you get

 

normal cocks/cinnamon cocks /ino

albino hens

and

lacewing hens

and cinnamon /lacewing cocks

 

as you see not all the /s are the same its as some sex linkages overide others

so as these chicks come from splits in first place (father being albino/lacewing)

the chicks them selfs may only pass on one of the characteristics

 

mabe this bird came from cinnamon breedings as well farther down his history

and the cinnamon has just over riden the genes untill now ?? just an idea

im probbly way off

you did say something about lines of normals so,, love to find out out come of his fathers breeding to the hen now placed with
