Tempranillo grown to be considered the state's signature grape. In Oregon, the grape was introduced by Earl Jones of Abacela Vineyards and Winery, in the Umpqua Valley AVA. Their climate (hot during the summer day, and cool overnight) seems to be perfect for the Tempranillo grape. In Australia Tempranillo is grown in the McLaren Vale region, and also North East Victoria. Tempranillo has also been introduced by some wine producers in Thailand. The varietal is extensively grown in Argentina, Chile, and Mexico. In Washington state, Tempranillo was one of the varieties pioneered in the state by Red Willow Vineyard 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
