Mmm....what if, there's "unique, personal" Semblances, and "blood, genetic" Semblances? What if they can "mix" with each other?

For example, by your own Soul, your Semblance would do X, while thanks to genetics your Semblance would do Y. So in the end, one of 2 things happen:

1) You get one, or the other.

2) You get a mix of both.

Just like how, in real life, you may get 1 of 2 genes of the same type, or you may get a mix of both, even if more rare.

In Schnee's case, the Summoning effect would be the Genetic Semblance, which both Weiss and Winter have, while Weiss's Glyphs do more than just summon (the "Unique" Semblance), which is what allows her to use Dust through these Glyphs, and even combine them to create interesting effects like Haste.

For all we know, Winter can only make White Grimm, while Weiss could create Fire Grimm or Stone Grimm.

Of course, I say this mainly because I don't remember Winter using her Glyphs to use Dust like Weiss does all the time. And I'm aware that that in itself can be easily explained: She's a pro, not a noob like Weiss, she doesn't need Glyphs to use Dust skillfully.
