Apparently it means Bloodline Selection, my interpretation is that Dust Release, the only known Kekkei Tōta, is something that was achieved through selective breeding. Kurotsuchi, Onoki's granddaughter has Lava Release. So it's possible that a Dust Release user can be created through breeding of individuals, one of which who possesses Lava Release and another individual who possesses some other unknown advanced/combined nature.

So Dust Release might very well be a combination of 2 different nature transformation Kekkei Genkai, one of them being Lava Release.

If it's true that Dust is part Lava, then Dust Release can be either Lava Release + (Earth+Wind) or Lava Release + (Fire+Wind)

Earth + Wind is considered to be 'confirmed' here, but by that I mean only presumed unless proven otherwise to be Magnet Release, but I personally like to think it's Crystal Release. While Fire + Wind is Scorch Release....

So Dust Release is Lava Release + Magnet Release, Lava Release + Scorch Release or according to my personal headcanon, Lava Release + Crystal Release, since I'm not convinced that Earth + Wind = Magnet quite just yet.

Even though a single character's nature transformation sheet in a full of errors databook indeed implies that Earth + Wind is Magnet, I'm still waiting for a more proper and direct confirmation that cannot be doubted.

And yes, I know Crystal Release appeared only in an anime filler, which automatically makes it 99,99% likely to be non-canon, but there is a small chance that Crystal Release is from Kishimoto's brain.

Lava + Crystal = Dust would fit so nicely... while Lava + Magnet or Lava + Scorch not so much, so I'm biased towards Earth + Wind being Crystal not Magnet.
