Here is an article by U.K. poultry geneticist Grant Brereton. In it he claims the Lav link with the "tail shredder" gene can be broken. Apparently they have succeeded in doing so in the U.K., so that gives us hope that Ameraucana breeders won't have to always breed back to black to avoid it.

Thanks Mike. He also mentions the Isabel that we have spoke about so this article hit a lot of topics.
QuoteIn Holland and Germany they have a color called ‘Isabel,’ which is created when the lavender gene is added to Partridge (or a similar variety such wild type or double-lacing).The nomenclature does vary and not all agree what ‘Isabel’ should look like. And, on some parts of the Continent, what we know as Millefleur in the UK is actually referred to as ‘Porcelain.’

It should perhaps be noted that in the U.K. they call our Black Breasted Red varieties "partridge." And what we call partridge, they call golden penciled.
