Gamay Beaujolais Gamay Beaujolais Gamay Beaujolais is a varietal designation for a Californian grape variety, an early ripening clone of Pinot noir. In the late 1930s, an early pioneer of the American viticulture, Paul Masson, brought with him several Burgundian grapes for his winery in California. One of those grapes he believed to be the Gamay variety from the Beaujolais region in France, which in the 1940s University of California at Davis (UCD) researchers christened "Gamay Beaujolais". In the late 1960s, UCD scientists decided that Gamay Beaujolais was a clonal selection of Pinot noir, and that California's version of the true Gamay
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
