Tempranillo in the Penedès, Navarra and Valdepeñas regions. Tempranillo is known under a number of local synonyms in different regions of Spain: "Cencibel" and "Tinto Fino" are used in several regions, and it is known as "Tinta del País" in Ribera del Duero and the surrounding area, "Tinta de Toro" in Toro, "Ull de llebre" in Catalonia, and "Morisca" in Extremadura. The grape plays a role in the production of wines in two regions of Portugal, central Alentejo and Douro. In Alentejo Central it is known as Aragonez and used in red table wine blends of variable quality, while in the
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
