"They" have been known to harvest genetic material not consciousness.
That's just some more Newage Sewage recently made up by some Wannabe UFO Guru
to hook some Believers.
No real Experiencer will ever fall for that crap.
Actually there are a number of examples where this topic is brought up
"They" told Streiber "we recycle souls" which imo is another term for conciousness, that unique experience set that makes each of us unique.
The collins elite think the same thing
Rather, the group - which calls itself the Collins Elite - concludes that the "aliens" are, in reality, literal demonic entities that are trying to seduce us with a false lure of supposed alien technology, and to - quite literally - steal and farm our souls. The group claim to have discovered evidence that these demonic entities - that seem to utilize a weird combination of advanced technology and archaic rite and ritual - derive a form of "energy sustenance" from the human soul or life force.
And while i dont subscribe to the demons aspect, there may be something in the idea.
Just when will this ultimate life-affirming feat be possible? In Kurzweil's estimation, we will be able to upload the human brain to a computer, capturing "a person's entire personality, memory, skills and history", by the end of the 2030s; humans and non-biological machines will then merge so effectively that the differences between them will no longer matter; and, after that, human intelligence, transformed for the better, will start to expand outward into the universe,
By 2040 you will be able to upload your brain... - Science - News - The Independent
That sounds exactly like what the collins elite are describing, and we are learning to do it.
According to Ian Pearson, a British futurist, death will be a thing of the past by 2050.
Pearson is one of many futurists, cybernetic experts and artificial intelligence researchers whose thoughts are converging on the same basic idea: Why not upload everything that's in the brain—everything that makes a person who they are—into a computer and then download it again into a new body?

Perhaps the genetic material is being collected to clone this "new body" , perhaps they need to match your genetic material to your conciousness to stop what we call in organ transplants "rejection"
We are about to perfect this technology someday, perhaps "they" already have and are transbiological in nature.
Even the old religious texts echo the meme, The jesus character says when you die, you go to live for eternity in the heavens with a "new body", an optimised body free of the corruptions found in our native bioforms.
Our own technology is rushing towards this reality......................
One day we may ourselves be able to live in the heavens in optimised clone bodies, and be able to do so for a very long time perhaps even eternity, when one body wears out, nip back in time to the original native bioform and get a sample and create a new one to transfer to. Perhaps thats why these samples are typically taken when you are young, before the DNA starts to get corrupted by free radicals, pollution, radiation and bad lifestyles
