Why do apples trees have to be grafted?

Asked by LostInParadise (31915points) July 18th, 2009

From what I have read, apples from apple trees grown from seed are too bitter to be eaten and can only be used for making cider. In order to propagate apple trees, a branch from an existing apple tree is grafted onto some other tree.

What is it about apple trees that makes this necessary? Other fruit trees can be grown from seed. I am assuming that the original trees for varieties like Delicious and Macintosh originally came from seed. Why couldn’t they be cross-bred to produce more trees of the same type?
