Combination of two black diluters like sex-linked choc and blue could cause a zonal distribution alike Id and blue. The latter gave a bird with blue at the outer ends: head, feet, primaries, tail looked blue because the dun was located on the flag nearest to the body.
As if the distribution started in the middle of the bird (lowest point of the breast bone), that bird was dun/red coloured and the blue on the outside.

Well I know, it's getting more updates than viewers but it's getting there.

Added functionality:
"Show examples" to fast choose the parent genotypes.
In the result genotypes grid you can choose an F1 animal male/female; this becomes a new parent.
You can call the html page with a limited set of dutch color names like this:

Please report any bugs.
I am testing with ie7 and new firefox.
Any strange behaviour in layout?
For example the pictures appear behind the lists.
This is how it should look.

This thing is absolutely fantastic - thank you so much for all the work you must have put into it!

I know so little about genetics, and this will help me learn because you can see everything displayed in front of you.

Hello Henk,

this is what it looks like using:

IE 7.0.5730.11
WIN-XP Pro 5.1.2600 SP2
resolution: 1024 x 768

directlinks: http://www.krassesrudel.at/forumbilder/thecoop/henk1.jpg
http://www.krassesrudel.at/forumbilder/thecoop/henk2.jpg

It looks to me as if the images hide the lists. Just realized the pics don´t hide the list but rather push it downwards. Same with Firefox 2.0.0.11, BTW.

Hope this helps and best greetings,

Joachim

Hi Joachim,

Yes that's right, it pushes down now. I removed the "layering" because even ie6 messed it up.
Thanks for testing.

You´re welcome Henk!

Ah, I see. Good work, BTW! The calculator works fine and seems to use only little recources, also it never crashed while I tried sevral combinations, cool. Good done! I´m sure you know that there are still some pics missing, I guess you´re working on these already?;-)

Best greetings and thanks for this great tool!

Joachim

Fixed a few bugs again.
Firefox: choosing an example didn't work

Joachim,
The possibilities are endless!
There are 18 loci
E I Bl S other
5*6*3 *3*2*2*2*2*2*2*2*2*2*2*2*2*2*2
*2 male/female
=8847360 pictures if your strict!
got 300 (the most common in my book), and my webspace is already quite full... wink

Blackdotte, actually test matings are being carried out between chocolate and splash wyandottes - choc male over splash female, so the resutant guaranteed choc/_ Bl/bl+ daughters would be indicative of the combination effects of Chocolate and Blue. Should it produce a nice colour, then no doubt a Chocolate male will be used back to the F1 and selection can be made for the new colour which will obviously be 50%.

Cheers, hope you well, Grant

I would suspect the combination of the Chocolate gene(sex linked recessive) and the Blue gene(incompletly dominant) in chickens, would behave similar to the combination of the Brown gene(sex linked recessive) and the Blue gene(incompletly dominant) in ducks.
The combination of the Blue gene, in the heterozygous state, and the Brown gene(for a genotype of Bl/bl, d/d) produces a creamy blue kind of colour in ducks(where black pigment is present), sort of similar to heterozygous Dun Id/i in chickens.
Blue in the homozygous state in combination with the Brown gene produces the similar Dun colour again, but of a lighter shade.
In ducks it seems that a build up of modifier genes can "tip the balance" of the combined colours to be either more bluer or more browner.
