Different apples are produced by different varieties of apple tree.
There is only one species, Malus domestica.
Most all varieties of apple are propagated by “grafting”. A cutting from the desired type is grafted to a more vigorous root stock.
The root stock is often propagated by rooting cuttings from a parent tree of that type.
Apple trees grown from seed will not breed true.
You can graft multiple varieties on a single root stock if you like.
