As I understand it, grafting is used when trying to grow apples that taste like apples from another apple tree you like. Reason being the genetic variation of the seedlings means that the apples that come from the seed aren’t likely to taste like the apples from the host tree.
But when the tree with the grafted branch grows, is the grafting done in such a way that you only get the desired apples to grow? If so, how? Since presumably the host tree also has its genetic predisposition from its seedling. Does that change when you graft a branch into it?

The grafted branch is from Tree A and therefore has Tree A’s DNA
The branch is receiving nutrients and water from the host tree, not DNA
When the branch bears fruit, it is the fruit of the branch, ie the branch’s DNA, which in the case of a graft, means the fruit comes from Tree A, which is being fed with nutrients by the host tree
