The forbidden fruit in the Garden of Eden was not an apple. We do not know what it was. It was probably unique, and not existing any more. Here is what the book of Enoch says about the Tree of the Knowledge of Good and Evil.

Enoch 32:3-6
And I arrived at the Garden of Innocence, and saw at a distance from those trees, more trees, with large, beautiful branches, attractive and magnificent, and also the tree of knowledge, whose fruit they eat and know great wisdom. This tree was as tall as the fir tree, but its leaves like the carob tree, and its fruit like a very beautiful cluster of grapes, and its smell spreads a long way from the tree.
At that time I said, “How beautiful this tree is, and how pleasing its appearance!”
Then Raphael, the holy angel who was with me, answered, “This is the tree of knowledge, from which your forefather ate, and your ancient mother, which when they ate they learned of knowledge, and their eyes were opened, and they knew that they were naked, and they were driven from the garden.”
