The common baker's yeast (Saccharomyces cerevisiae) was the first non-bacterial living thing to have its genome sequenced, back in 1996. However, when the sequence of that genome emerged it appeared that the scientists were seeing double -- the organism seemed to have two very different versions of many of its genes. How could this have happened?
