What is the difference between the fruit grown from the seed of the apple tree and the fruit

What is the difference between the fruit grown from the seed of the apple tree and the fruit of the grafted apple tree? Why?

An apple tree grown from seeds will not yield the same yield as a grafted one. When an apple tree grows from seed it is a wild apple tree, it does not have the properties that a grafted domesticated apple tree has. The same effect can be seen with lemon. If it is grown from a seed, it will not bear fruit, but if you pinch the chips of another, fruiting lemon, the first will also begin to bear fruit. This is due to the fact that due to wood chips, the plant receives the signs and properties of the plant attached to it.
