I just took another look at it on Day 106 when the term is used...and yeah, you're indeed right.

Mix Blood = Chaos Species

Basically...they have to prove that they aren't going to sow Chaos...but they're normally killed because of their extreme potential due to their ab ility to make use of Jobs  and  rank up.

It seems they've gotten SOME portion of his Absorption ability, as well...though I think that might simply be limited to absorbing power from enemies and whatnot...as there's been no mention of them absorbing and learning abilities (but there was an effect when they ate those antlers and stuff, so...yeah...dunno).
