The extractor consumes 50W of power when idle, and 200W when active. When active, a gene extractor will collect [[genes]] from humans to be stored into a [[genepack]]. Colonists can be ordered to enter the gene extractor either by right-clicking it with a colonist selected, or by using the on-screen gizmo. Prisoners can be loaded into the gene extractor using the on-screen gizmo. Once a prisoner has been selected, a colonist will haul them to the extractor. This job is considered "Hauling" instead of "Wardening". [[Quest]] lodgers cannot have their genes extracted.

The extractor consumes 50W of power when idle, and 200W when active. When active, a gene extractor will collect [[genes]] from humans to be stored into a [[genepack]]. It takes 12 hours for gene extraction to complete, during which time the occupant will be "suspended" and will not have their needs decay. Once extraction is complete, the occupant will be ejected, and a new genepack with 1 to 4 collected xenogenes will be dropped nearby. If it is not powered for 24 hours, then extraction will be canceled.
  
−
In order for a pawn to enter the extractor, they must have one or more genes aside from their melanin (natural skin color) and hair color genes, meaning that baseline humans are exempt. The extractor can still extract an occupant's hair color or non-natural skin gene, if present.
+
Colonists can be ordered to enter the gene extractor either by right-clicking it with a colonist selected, or by using the on-screen gizmo. Prisoners can be loaded into the gene extractor using the on-screen gizmo. Once a prisoner has been selected, a colonist will haul them to the extractor. Interestingly, the job is considered "hauling" instead of "wardening". [[Quest]] lodgers cannot have their genes extracted.
  
−
It takes 12 hours for gene extraction to complete. The occupant is not suspended during extraction, and will still have their needs decay. This means that a pawn may be starving or exhausted by the time they leave. Once extraction is complete, the occupant will be ejected, and a new genepack with 1 to 4 collected xenogenes will be dropped nearby. If it is not powered for 24 hours cumulative during the extraction, then extraction will be canceled.
+
Once extracted, the occupant will suffer from ''Gene Shock'' for 2 days, causing pain ({{++|5%}}) and lowering their [[consciousness]] ({{--|5%}}) and [[blood filtration]] ({{--|15%}}). They also gain the ''Genes Regrowing'' condition for 12 to 20 days. This does not have any direct effects, but will cause instant death if the pawn has their genes extracted before it wears off.
  
−
Once extracted, the occupant will suffer from multiple conditions:
+
Prisoners who have their genes extracted will have a {{--|8}} ''Genes Extracted'' [[mood]]let. Colonist moods are not affected by anyone's genes being harvested, including their own.
−
* ''Gene Shock'' for 2 days ({{++|5%}} [[pain]], {{--|5%}} [[Consciousness]], {{--|15%}} [[blood filtration]])
 
−
*''Genes Regrowing'' for 12 to 20 days. It does not have any direct effects, but will cause instant death if the pawn has their genes extracted before it wears off. This death is caused by destruction of the brain, so the [[Genes#Deathless|Deathless]] gene does not stop this.

=== Gene selection ===
 
−
Attempted number of genes to extract is weighted as such:
 
−
* 1 gene    -> 0.7 weight
 
−
* 2 genes -> 0.2 weight
 
−
* 3 genes -> 0.08 weight
 
−
* 4 genes -> 0.02 weight
 
−
 
 
−
After a number of genes to extract is selected, the following rules must be adhered to for selecting genes:
 
−
* Sum of all genes' metabolism score is required to be within -5 to 5 range.
 
−
* Archite genes '''cannot''' be extracted.
 
−
* Melanin skin color genes '''cannot''' be extracted.
 
−
* No duplicates.
 
−
 
 
−
If a gene has > 0 complexity, it has a selection weight of 3, otherwise its weight is 1.
 
−
 
 
−
=== Xenotype Extraction Table ===
 
−
The following table serves as a reference for which [[xenotype]]s have which specific genes. Bear in mind that many genes are not used by any xenotype, and must be acquired through [[trade]] or [[quest]]s. Archite genes cannot be extracted, despite appearing in the table.

Overall, gene editing is suprisingly inexpensive. A gene extractor, [[gene bank|bank]], and [[gene assembler|assembler]] only costs {{Icon Small|steel||{{#expr: {{Q|gene bank|Resource 1 Amount}} + {{Q|gene extractor|Resource 1 Amount}} + {{Q|gene assembler|Resource 1 Amount}} }} }} [[steel]] and {{Icon Small|component||{{#expr: {{Q|gene bank|Resource 2 Amount}} + {{Q|gene extractor|Resource 2 Amount}} + {{Q|gene assembler|Resource 2 Amount}} }} }} [[component]]s. You don't need to build the assembler right away, lowering the cost to {{Icon Small|steel||{{#expr: {{Q|gene bank|Resource 1 Amount}} + {{Q|gene extractor|Resource 1 Amount}} }} }} [[steel]] and {{icon Small|component||{{#expr: {{Q|gene bank|Resource 2 Amount}} + {{Q|gene extractor|Resource 2 Amount}} }} }} [[component]]s. This is often affordable for colonies that have the time to research Xenogenetics. You may want to build more gene banks as your gene collection grows, but you can toss out unwanted genepacks in the meantime.

Rather, the main cost of the extractor is ''time''. Each extraction takes 12 hours and has a cooldown of 12-20 days per person. And you'll get an entirely random set of genes; there's no protection against duplicate gene packs, for instance. Players that desire to use xenogenetics should plan ahead. Both colonists and [[prisoner]]s can have their genes extracted. If you want a specific xenotype's gene, then try and capture as many prisoners of that xenotype as possible, even if you don't want to recruit them. Don't shy away from extracting colonist genes, either - the extraction process is a very minor penalty, unless a colonist is currently suffering through a [[disease]].

−
In return, even simple [[xenogerm]]s can provide major benefit. For example, [[neanderthals]] have [[Genes#Robust|Robust]] gene, reducing ''all'' damage by ×75%. With a Great <skill> gene, it becomes very easy to reach (and maintain) a level 20 skill. Virtually every [[xenotype]] has at least one gene worth extracting and using. Don't be afraid with installing "incomplete" xenogerms; each xenogerm completely overwrites the last, and only costs 4 [[herbal medicine]] to implant.
