Apples originated in Kazakhstan several thousand years ago. There are over 7,500 varieties of apples, because apples from trees that grew from seeds very, very rarely resemble their parent plant in terms of quality and flavor.
The vast majority of apples available come from trees grown from cuttings of a handful of trees of that apple variety that produce good apples.
Bananas are very likely to have been domesticated in Papua New Guinea from an ancestor plant that has fruit with giant pits... nothing like the bananas we know and love today.
Don't do a Google Image Search on "wild banana" if you have tryptophobia and/or if you want to ever eat another banana again!
