Young Blonde Girl With The Orange Fruit

Today, navel oranges continue to be produced through cutting and grafting. This does not allow for the usual selective breeding methodologies, and so not only do the navel oranges of today have exactly the same genetic makeup as the original tree, and are therefore clones, all navel oranges can be considered to be the fruit of that single nearly two-hundred-year-old tree. The case is similar to that of the common yellow seedless banana, the Cavendish. On rare occasions, however, further mutations can lead to new varieties.
• Cara cara navels
Cara cara oranges (also called "red navel") are a type of navel orange grown primarily in Venezuela, South Africa, and California's San Joaquin Valley. The bright orange exterior of cara cara oranges is similar to other navels, but their interior is a distinctive pinkish red. They are sweet and comparatively low in acid.
It is believed to have developed as a cross between the Washington navel and the Brazilian Bahia navel. It was discovered at the Hacienda de Cara Cara in Valencia, Venezuela in 1976.
