No one mentions F1 hybrid? Mass produced vegitables and fruits are often first offspring of 2 distinct variety, carefully selected to inherit desireble trait from both sides but no guarantee for 2nd generation.

Kind of soft-lock drm bcs people need to keep buying the specific seed if people want max yield. (I’ve read article gathering seeds store brought tomato, the yields were unstable but they managed to iterate 6 generations or so. The “traits” of F1 offsprings stabilize around that so you can keep growing your own variety).

Heirloom seeds doesn’t have this issue, but they likely to have quirks compared to F1.
