Gala (apple) Gala (apple) Gala is a clonally propagated apple cultivar with a mild and sweet flavor. "Gala" apples ranked at number 2 in 2006 on the US Apple Association's list of most popular apples, after "Red Delicious" and before "Golden Delicious", "Granny Smith", and "Fuji" (in order). The skin color of the fruit is non-uniform. Recently, The US Apple Association has projected that the Gala apple will become America's favorite apple. The "Granny Smith", "Fuji", and "Honeycrisp" apples are expected to rank third, fourth and fifth, respectively. Gala apples are vertically striped or mottled, overall orange in color. They are sweet,
Morphism of algebraic varieties Morphism of algebraic varieties In algebraic geometry, a morphism between algebraic varieties is a function between the varieties that is given locally by polynomials. It is also called a regular map. A morphism from an algebraic variety to the affine line is also called a regular function. A regular map whose inverse is also regular is called biregular, and they are isomorphisms in the category of algebraic varieties. Because regular and biregular are very restrictive conditions – there are no non-constant regular functions on projective varieties – the weaker condition of a rational map and birational maps are frequently used
