Gamay from Pinot noir, another Burgundian grape. It was introduced by Amity Vineyards in 1988. In 1991, Rebecca's Vineyard planted Gamay and was one few Oregon vineyards selling the grapes. LaBete winery was the first to make a vineyard designate of Gamay from Rebecca's Vineyard. Since then, Rebecca's Vineyard stopped selling Gamay to those who would only blend into their Pinot Noir for flavor and color enhancement, and to only sell to those who would produce stand alone Gamay. Younger wineries like Division Winemaking Co., who are now the largest producer of Gamay in Oregon, have helped raise awareness and availability
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
