Undead Anatomy Spell and Bonus claw attacks

[wolfen]

So basically I am taking an alchemist with mutagen as his main trick and then Undead Anatomy 3 as his rank 6 spell.

So basically I am curious on if the claws gained from the UA3 and the mutagen power that gives 2 claws and a bite stack or is it I have to choose?

1) Spells don't have ranks, and Alchemist use Extracts, not spells.

2) You are limited by limbs for Claws, and heads for bites, so no more than you have available. Otherwise, you choose which Claws/Bites apply.

Also, check out the Mudra Skeleton, which has four arms.
