In 1820, an orange bush was discovered in Brazil, the fruit of which had no seeds. It was he who became the ancestor of the Navel orange. The absence of the bone was caused by a spontaneous mutation. Harmful to the plant, it turned out to be useful from an economic point of view. What is the harm to plants and the benefit to humans of this mutation?

1) without seeds, mutant plants in nature cannot reproduce sexually;
2) all modern seedless oranges are vegetative clones of the same plant, once discovered in Brazil, they are propagated vegetatively (by cuttings).
