Any ideas on how this works is it just the Primarks dna that they need or cells from their geneseed? Just seems odd that someone would have enough of anything for 100k other guys.

Ahh, thanks for the clarification about the Primarchs. I assumed they had progeniods but it is only Asartes who have them. Correct? So they use the blood, or other simple tissues to get DNA to create progeniods. This means that the "son's" probably had a new batch of cells, or I guess 1st generation progeniods, while everyone else had 2nd or older generations of geneseed. Let me know if this is correct.
Could this mean that if the Ultra's extracted blood from Guilliman they could create a new generation of Asartes, more like their Primarch than any others?

It's author error, he's conflating the gene-seed with the rumored cloning. The 'Son's of Horus' is what the whole legion was renamed post Ullanor, it wasn't a special group amongst the legion.

As part of Abaddon's original fluff he was rumored to be a clone of Horus due to their similarities and affection for one another. Obviously this isn't true with Abaddon not being a primarch himself.

Looking at the citation i've opened that page up. The actual text is 'it's rumoured that Abaddon may have been a clone-son of Horus himself, a direct creation of the Primarch's gene-seed'.

That bit about the primach's gene-seed is a reference to the cloning process. Abaddon was rumored be a clone of horus; he was cloned from the primarch's gene-seed.

Note however that it is just an apocryphal rumor and not actually true. He's not Horus' clone and there's not some group of legion members specially descended from Horus.
