“Because the mutation left the fruit seedless and, therefore, sterile, the only method to cultivate navel oranges was to graft cuttings on to other varieties of citrus tree. … Today, navel oranges continue to be propagated through cutting and grafting. This does not allow for the usual selective breeding methodologies, and so all navel oranges can be considered fruits from that single nearly two-hundred-year-old tree: they have exactly the same genetic make-up as the original tree and are, therefore, clones.” http://en.wikipedia.org/wiki/Orange_%28fruit%29
