Apples are wildly genetically unstable, meaning that if you plant the seeds from a specific apple, the resulting tree will produce fruit completely unrecognizable from its parent. To maintain consistent varieties like the honeycrisp or the granny smith, farmers have to physically clone the trees by grafting branches onto existing rootstocks rather than planting seeds. Every single commercially viable apple you have ever eaten is the result of thousands of years of aggressive botanical cloning because natural apple genetics are chaotic, unpredictable, and frankly, a total mess. It is deeply unsettling to realize that the quintessential symbol of wholesome agriculture is actually a stubborn mutant that requires intense human micromanagement just to avoid reverting back to a bitter, tiny crabapple. Nature basically wants apples to taste terrible, but human stubbornness refuses to allow it
