Thing with being an Anodite, it's not exactly something in the body, more like in the mind/soul, even if it can be hereditary. Ben and Gwen's parents aren't Anodites because they don't have "the spark". Ben isn't either. Gwen is because she has the spark, but she's 100% human genetically speaking. The 1/4 Anodite part is more astral, spiritual.

For a hybrid to become a full-fledged Anodite, they need to separate their "true" form from the one that looks like a normal body. To do that, it usually requires to destroy the hybrid's body. Surely, it kind of looks like dying (and yeah, it kinda felt like Verdona was going to murder her granddaughter), but it's more like taking off a full-body mask, like Verdona and Sunny do to reveal their Anodite forms. So, in a hybrid's case, they need to destroy their body to let their true form come out, "purified", so they become a full Anodite.
