Durif is a grape from southwest France, widely grown in California as Petite Sirah and is permitted in Rhone Rangers wines. In 2002, after DNA testing by ampelographers showed that Durif was a cross between Peloursin and the popular Rhône grape Syrah, Petite Sirah was officially voted in as a member of the Rhône Ranger varieties. The main white varieties are Bourboulenc, Clairette blanc, Grenache blanc, Marsanne, Muscat Blanc à Petits Grains, Picardin, Picpoul blanc,
Petite mutation and exhibit Mendelian 1:1 segregation. Neutral petites (rho–N): Neutral petite when crossed to wild-type, all offspring are wild-type. It has inherited normal mitochondrial DNA from wild-type parent, which is replicated in the offspring. Suppressive petites (rho–S): crosses between petite and wild-type, all offspring are petite, showing "dominant" behavior to suppress wild-type mitochondrial function. Most petite mutants of "S. cerevisiae" are of a suppressive type, and they differ from neutral petite by affecting the wild-type, although both are a mutation in mitochondrial DNA. Mitochondrial genome of yeast will be the first eukaryotic genome to be understood in terms of both structure
