Apples and Genetic Diversity

Apple trees are produced by cloning. This means that most commercial apples in the world are clones of only 5 individual trees. Apples thus suffer from a drastic lack of biodiversity. This makes it easy for pests to evolve to overcome the trees’ natural defences. Farmers counter by dousing more pesticides on apples than any other crop. So, when you get an apple with some insect damage, this is a Good Thing™ This is a sign your apple was not soaked in pesticides.
