Vespolina name are still unclear. Through its parent-offspring relationship with Nebbiolo, Vespolina is a half-sibling of several Piemontese wine grape varieties including: Bubbierasco, Brugnola, Freisa, Nebbiolo rosé, Negretta, Neretto di Bairo and Rossola nera. The grape Vespolina is known under a variety of synonyms. These include Balsamina, Canneta, Croattina, Guzetta, Guzitta, Guzzetta, Inzaga, Inzagre, Massana, Nespolina, Nespolino, Novarina, Solenga, Ughetta, Ughetta di Caneto, Ughetta di Canetto, Ughetta di Canneto, Ughetta di Fassolo, Ughetta di Solenga, Uva Cinerina, Uva Rara, Uvetta, Uvetto, Vespolino, Visparola and Vispavola. Vespolina Vespolina is a red Italian wine grape variety that is planted in Piedmont around Gattinara
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
