I don't know where the rest of my post went, somewhere into cyberspace, but here it is.



All genetic traits are NOT multigenic, or polygenic which is really the correct term. Polygenism doesn't just mean that multiple genes are affected, it means that they also have a quantitative affect on the phenotype. Things Kahl albinism are simple recessive traits and are not polygenic. The amount of color in an individual is however. I'm not always a fan of Wikipedia but this article is actually very accurate: http://en.wikipedia.org/wiki/Quantitative_trait_locus



If you don't like Wikipedia, try this article I had to read several years ago in AP Biology. It goes very in depth into the mathematical aspect of polygenism, but if you skim through it makes the concept much easier to understand. http://www.genetics.org/cgi/reprint/147/3/1423?maxtoshow=&HITS=10&hits=10&RESULTFORMAT=&fulltext=polygenic&andorexactfulltext=and&searchid=1&FIRSTINDEX=0&sortspec=relevance&resourcetype=HWCIT



I also don't agree that anything can be a line. A line is created through generations of selected breeding by individuals that have proven to have the same reproducible characteristics. People surely will try to pass animals off as being descendants of lines that they aren't, which is a shame and very wrong. Breeders who have taken the time and effort to create a line whether it be in boas or dog breeding deserve to have their name on it and have people that continue to line breed their animals follow the same care when selecting breeding pairs. That's all just my two cents though.
