Gamay Blanc Gloriod variety, but DNA fingerprinting showed that along with Chardonnay and Aligoté, it is one of many grapes to be the result of a cross between Gouais blanc (Heunisch) and Pinot. Gouais blanc was widely grown by the French peasantry in the Medieval ages. Other Gouais blanc/Pinot crosses include Aubin vert, Auxerrois, Bachet noir, Beaunoir, Franc Noir de la Haute-Saône, Gamay, Melon, Knipperlé, Peurion, Romorantin, Roublot, and Sacy. The yield of Gamay Blanc Gloriod is variable; it produces small, cylindrical bunches of small grapes. Gamay Blanc Gloriod is grown in its home territory around Burgundy. none Gamay Blanc Gloriod Gamay Blanc
Petite mutation Petite mutation petite (ρ–) is a mutant first discovered in the yeast "Saccharomyces cerevisiae". Due to the defect in the respiratory chain, 'petite' yeast are unable to grow on media containing only non-fermentable carbon sources (such as glycerol or ethanol) and form small colonies when grown in the presence of fermentable carbon sources (such as glucose). The petite phenotype can be caused by the absence of, or mutations in, mitochondrial DNA (termed "cytoplasmic Petites"), or by mutations in nuclear-encoded genes involved in oxidative phosphorylation. A neutral petite produces all wild type progeny when crossed with wild type. petite mutations can
