Sexual reproduction provides genetic diversity through recombination. This genetic diversity may serve the population well as the environment changes or as the population expands into new environments. The adaptability resulting from genetic diversity is the major advantage of sexual reproduction over asexual reproduction, although sexual reproduction can also break up well-adapted combinations of alleles through the same process of recombination.
Asexual reproduction is the only way of raising plants such as navel oranges, all of which have been reproduced from a single tree found in on a plantation on the Brazilian coast in the early 19th century.
