why cant a grey-green be split for blue, as blue is a recessive gene it means any thing can be split blue.

also isn't gery a dominant colour, so if you put 2 greys together you can still get green as it depends on the parents of the grey,

cause it is dominant they can be sf or df

so if you put 2 sf's together you can get green, grey sf, grey df,

 

Well here's my understanding of the colour factor in budgies...

 

A budgie can hold two colour genes in each bird....

 

Green is dominant over blue,

Blue is reccessive,

Grey is dominant over blue, but co-dominant with green.

 

for a bird to be Greygreen, it cannot be split to blue because like I mentioned, they can only have two colour genes.. in this case, one grey gene and one green gene... and because grey and green are co-dominant, they show up together therefore giving greygreen birds. Can't have blue as there are no more 'gene' for colours.

 

As with Grey, again, it is co-dominant with green. and because grey is considered as 'blue series birds' or white base bird, the green isn't present in any grey birds. However it can be SF grey or DF grey.. in the case of the SF greys, it can only be split to blue, and not green as green isn't recessive to grey.

 

and if you put two SF grey together, you can get blue, SF grey and DF grey.

 

 

edit... after all that... you're almost right in saying that anything can be split for blue... all except for greygreen.

 

I hope that makes sense.

Here she is having a cuddle with an adopted sibling

Sorry to tell you but a Grey Green can be split to Blue.

 

I have paired two Grey Green Spangles and ended up with Spangles in Grey green, Grey, Green and Sky Blue. Also a Double Factor and found out the cock is also split to Opaline.

Daz,

 

how can it be? I mean genetically, I didn't think you can have a 'third' colour gene right?!?!? so you can have either SF or DF, I don't think I've ever heard of having triple factor colour gene. unless of course grey green genes somehow are combined to become a single factor bird? which I really dont think that's possible either.

okay you are a way. They are very good chicks. Are the pair down for another round or is that their second?

 

First round of chicks and Mum is scraping the nestbox today in preparation for more babies

 

**First egg for second round laid today

I removed 3 chicks from the nest to the breeder cage floor

others went into the kindergarten cage

If you have a green split to blue and you pair it to a grey, what do you get? Remember that green is the only colour that will mix with grey. So you get a grey green split to blue. It can also be split to a sex linked. eg Opaline, cinnamon or ino. Now knowing that if you have a green split to blue split to ino and pair it to a grey you can get a grey green split to Blue and ino. If it is a cock and you pair it to a green, you can get a green, grey, blue, grey green, lutino hen, or albino hen. - Think about that one

okay I just read through some genetics book... and it's darn confusing!! but in the end I got that they can be split for blue if they are like heterozygous or something or rather. I stand corrected.. anything CAN be split for blue.. but in the book I read, it says that it can only produce skyblue?!?! and that's 1 in 16 chance only.

 

Anyway, thanks Daz, you got me reading...

heterozygous is also known as SF on here Homozygous (sp?) is DF

Oooohhhh... soooo that's making a bit more sense now... sooooo Hetero is single and Homo is Double factor..

okay gotcha.. thanks Nerwen...

......thats an interesting way of thinking about it.. It just means that Hetrozygous has two differnet Allele (Genes) and Homozygous has two simalar Allele (Genes).

whatever they are, they are beautiful!

The grey gene and the yellow series genes are in diffrent loci. They may not even be on the same chromosome( actually I don't think they are because then they would be linked, which they aren't). Grey is not another allele of the yellow series. There is only two alleles for that loci and that is yellow based and white based.

The grey gene is in a different locus and it has only 2 known alleles. Grey is not codominance, it is incomplete dominance, which is very different. Thus you can have a grey white base bird, or a grey-green bird which is a grey bird in the yellow series.

 

Getting back to Bubbles's cinnamon chicky. It is an opaline. My Nikio is a violet opaline and her wings look spangle on the top, but with normal flights. Her tail feathers are navy blue, but they have white splotches all the way down them. Opaline messes with the wing markings as well as the colour and thus, you are likely to get some spangly looking wings. However you look closely and you see the shaft of the feather is still pigmented. Spangles, don't have that. Therefore that baby is a cinnamon opaline, which is very very likely to be a girl.

 

Just on a side note, i have a cinnamon opaline spangle violet yellowface2.

 

Note: Alleles and genes are not the same thing. You have a gene. For example the base colour gene. The alleles are different forms of that gene. eg, yellow base and white base. The loci or locus is the place on the chromosome where that gene occurs.

I agree, she is definetely Opaline-Cinnamon (occured due to crossing over between opaline and cinnamon genes.)

 

This budgie has to be a female due to sex-linkage cinnamon and opaline genes. Because both parents have normal black wing pattern, the father has to have Opaline-Cinnamon or Opaline and Cinnamon genes hidden...female babies get always their X chromosome from the father.
