Laced Blue Ameraucana
Christie Rhae:
John, post number 18... THAT is what I am talking about! lol
That is the lacing that I want. What a beautiful bird. You just cannot get that with Ml alone.
Here is a link to the breeders site that I am trying to get andalusians from. He has sent me new pics too but I do not have authority to post them.
gg.cochinsrule.com Go to the PRESERVATION BREEDS tab.
Previously I have not posted exactly where I am trying to get my andalusians from because this breeder actually says on his signature on BYC that he is not selling chicks or eggs. I guess he has pity on me and is trying to help me get some andalusians so is willing to work with Hawaii to get permits, etc. He looks like he has been doing this awhile. Some of you may know him?
What ever these birds have that is making their feathers look like that...I want that in my blue ameraucanas.

That bird has what it takes and I assume that includes Co.
Some of us have shown blue Ameraucanas without lacing for decades. Some looked pretty good...the birds not the exhibitors. ;)

If you had this Blue Andalusian hen, what cross would you make to prove that she carries the CO gene?
Assume that she is E^R CO plus all of the other stuff but we only want to prove CO in this mating.

Carefoot in 1988 says yes to Co.

Compo in 1991 says no to Co. FYI, he uses Lg (Lacing gene) rather than Pg (Pattern gene).

Both of those studies found the birds were based on E, but Okimoto did a study with hatchery birds and found them to mostly be ER.

Some of us speculated that Andalusian blue used ER instead of E because ER would be more amenable to secondary pattern genes like Pg. I recently tested some Andalusian Blues from McMurray. I had a mixed batch of chicks so I could only tell the gray ones as blues the blacks could have been something else. There were three gray chicks that produced gray chick feathers. Two were homozygous ER ER and the third was heterozygous E ER. My guess is that E probably causes the dark birds and that the show quality birds are probably ER.

Does anyone have links to newer studies?

YOU care. Otherwise you would not have done the research that you have on the lacing feather patterns. Anyone can select the best laced Andalusians and cross to black or blue Ameraucanas and then select for the best laced offspring. But by the nature of your posts it\'s obvious that you are striving to learn more about this stuff and understand it. You also listed a quote, something about not believing what you are told or hear but following your own understanding. If that\'s not someone who cares about finding out about this for yourself, I don\'t know who is.
Why does it matter? Because if we are content to follow the common wisdom, we won\'t strive to develop varieties like lemon blue modern games with dark blue lacing or blue wheaton ameraucanas with laced blue breasts because common wisdom tells us it is not genetically possible.
