Posted March 12, 200817 yr Just a question I have noticed with my breeding that any cock or hen that is opaine has opaine babies I suppose it is % ... Stasky & Margoo each clutch ( apart form the last one) had 1 x Lutino 1 x Clearwing 1x Dilute 2 x opaine's Out of 4 rounds I only got 1 skyblue opaine 1 x White clear wing the rest are yellows and greens ..... But Michael who is a YF2 Opaine his kids (12 ) are all opaine apart from 1 dompied clear wing the mum was a Mauve Clearwing .... i got 1 colbalt out of all of them .....
March 12, 200817 yr I have this pair I dont know about the % etc but i do know that i have had Not ONE opaline from 3 clutches... dont know about their current clutch as they haven't feathered up yet. All babies have been either normal greens, blues or pieds...
March 12, 200817 yr Opaline Is a Sex linked Gene I hope this helps you Opaline x Opaline = 100% Opaline Opaline cock x Normal hen = Normal / Opaline cocks Opaline hens Normal / Opaline cock x Opaline hen = Opaline cocks Normal / Opaline cocks Opaline hens Normal hens Normal cock x Opaline hen = Normal / Opaline cocks Normal hens Normal / Opaline cock x Normal hen = Normal cocks Normal / Opaline cocks Opaline hens Normal hens Edited March 12, 200817 yr by *libby*
March 12, 200817 yr Author Nope Libb that has just confused me ... Sex link.... This is how i understand sex link for instance albino is a sex link Now Snowhite (albino *RIP) out of a clucth of 4 had only 1 Albino who is a male??? So the sex of the parent that is a sex link gene will produce the opposite sex baby ????? ( just realised I've been spelling Opaline wrong (Laughing out loud) ) Opaline cock x Normal hen = Normal / Opaline cocks BABIES, Opaline hens BABIES But Normal cock x Opaline hen = Normal / Opaline cocks BABIES, Normal hens BABIES ... Where is the sex link ????? We all know why Neat failed Science at school
March 12, 200817 yr okay well basically... If the male doesn't carry the gene No chicks can be born showing it... If the cocks split opaline you'll get opaline hens and some split for opaline cocks If only the hen is opaline you'll get normal hens and split for opaline cocks if both parents are opaline, all chicks will be opalines of both sexes If the cocks opaline you'll get opaline hens and cocks split to opaline Does that help The reason you got a male baby albino from that pairing is because the cock is split so you had a possibilty of = albino cocks Normal / albino cocks albino hens Normal hens And you happened to get the albino cock :hap: NOW does that help ?

Opaline is another sex linked variety which is carried by the cock. For sex linked stuff I usually think along these lines. 'The cocks could be split for any number of sex linked factors but the hens are what they are'. The sex link factor or factors is carried on the X chromosome of the cock bird. So the cock can have a number of varieties hidden in the genes because it has two X chromosomes. The hen has XY. That's why the hen determines the sex, it can pass on either a X to make a young cock or a Y to produce a hen. The combination you describe is quite a mixed bag where you would have to work out percentages with a mix of dominant and recessive varieties. Would end up quite a brain strain

March 12, 200817 yr it is the opposite of humans. You know how things like colourblindness is sex linked, as in most people with it are male? that is because i people, the male has the XY genes. Opposite in budgies. Females have the XY genes. Very few characteristics, in either, are carried on the Y gene, so whatever is on the X gene dominates. So if a male budige that gives a X gene to a young budgie, with the opalien characteristic, and the femal give as a Y gene, then the bird will be female. Since the C gene carries little or no characteristics, then the budgie will be female and opaline. If the male budgie gives the X gene with the opaline gene, and the female is not an opaline, therefore her genes are XY, btu no opaline characteristic on her X, but gives and X gene, the bugie will be male, as it has XX genes. Dad has said be opaline, mum has said do not be opaline, not being opaline is dominant, so the baby boy will not be opaline, but will be split to opaline.

March 12, 200817 yr Well in that case (Laughing out loud) Spangle is a dominant gene...but there is a single factor which means they carry 1 Spangle gene and that is when you will see the marking on the back then ther is the double factor Spangle which means the birds carries 2 spangle genes and the bird will be either completely yellow or white and it may have some suffision. Double Factor Spangles, have iris rings and blue cere, this is one way you can distinquish them from Dark Eyed Clears and Inos. The sex-linked genes all work the same so just know the basics don't worry about the x and y stuff - it makes it easier but if confuses you right now don't worry about it just know these facts. Females - when they carry a sex-linked gene it is visual it will never be masked and all the males in the nest will be split to the sex-linked gene (example opaline) but the gene will not be visual Males - when they carry a sex-linked gene 1 gene = it will not be visual & and they will pass the gene any female offspring (which will be visual) & males will not be split 2 same gene it will be visual on the cock bird and he will pass down to any female (they will be visual) & males will be split (non visual)
March 12, 200817 yr Hi Neat, Spangle is a "dominant trait" so a large majority of chicks will be born spangle. I figured I wouldn't put in all the charts as they can be confusing if you aren't into genetics. If both parents are spangle all the babies will be spangle, some will even be double factor spangles that look like ino's as they are all white or all yellow, with black eyes. Hope this helps, Feathers.
March 12, 200817 yr Author This is officially the most confusing thread...Get use to it (Laughing out loud)Hi Neat,Spangle is a "dominant trait" so a large majority of chicks will be born spangle.
