Because it's the first gen of a cross-pollinated variety. They take two "pure" lines of species that are produced by self-pollinating the same variety for many generations and then cross-pollinate. This creates a hybrid. It tastes and looks great, but it yields seeds that are a result of _self_pollination, so some original traits get suppressed and some dormant traits activate. I didn't know that either, but apparently it's basic botany. Google up "F1 F2 seeds".
