Gala (apple) total volume of the commercial production of eating apples grown in the UK, often replacing Cox's Orange Pippin. Many sports of Gala have been selected, mostly for increased red color, including the popular "Royal Gala". The original cultivar produced fruit with orange stripes and a partial orange blush over a yellow background. Since then, several un-patented sports have been recognized. Additionally, more than twenty sports have received US plant patents: Unpatented varieties include: Auvil, Imperial Gala apples are grown from May through September in the northern hemisphere, but, like most apples, are available almost all year through the use of
Morphism of algebraic varieties that the category of affine varieties can be identified with a full subcategory of affine schemes over "k". Since morphisms of varieties are obtained by gluing morphisms of affine varieties in the same way morphisms of schemes are obtained by gluing morphisms of affine schemes, it follows that the category of varieties is a full subcategory of the category of schemes over "k". For more details, see . A morphism between varieties is continuous with respect to Zariski topologies on the source and the target. The image of a morphism of varieties need not be open nor closed (for example,
