Is it possible to remove bad genes from someone?

[Mr W]

I have a Neanderthal in town. Strong, hardy, dumb as a rock and can't hit the broadside of a barn in combat. Is it possible to remove some of the bad genes from him without harming the good traits? Unrelated, if a Neanderthal and a Baseliner have kids what happens? 50-50 on the genes?

You can't "remove" germline genes from a pawn, but you can overwrite them by adding xeno genes that counter them, for example adding the Strong shooting xeno gene would disable the poor shooting germline gene.

But do keep in mind that a pawn with only active good genes and without active negative genes to balance things will have a horrible metabolism and severe hunger issues (have to eat more often).

When it comes to children and genes passed on there is a bunch of rules for it and unless its a gene both parents have its also largely RNG based (btw baseliners have no genes to pass on other then hair and skin color).

I believe through dev mode you can remove genes. I think I saw the option in there recently though I haven't used it myself

The kids will have a 50% chance to inherit each gene, yeah.

Unfortunately germline genes can't be deleted, but xenogerms can override them in specific cases. If you can extract or buy the opposing gene, putting it into a xenogerm and implanting that may solve your issue.

Not necessarily. There is also a complexity and maximum metabolism value that is rolled that might prevent genes from being inherited (As a example, say one gene fails to be rolled, that might make it impossible for the next gene to be rolled since it might go above or below the metabolism limit on the child). The order the genes are rolled for might also mess stuff up.

That said, they are changing this around to make genes more easily and reliably passed down in the next big patch (the one that is in unstable at the moment). Don't know the details.

I wonder why neandethals would exist. They're extinct. Did somebody Jurassic Park them back to life and spared no expense?

Well the SLOW LEARNER trait was really killer for taking Neanderthals in my games so i just remove it completely from them,if you wanna edit Xenotypes presets (MAKE A COPY OF ORIGINAL FILE) then go to Rimworld folder >Data>Biotech>Defs>GeneDefs there is XenotypeDefs file just open in wordpad(or any text editor) and change to your liking, if you just wanna remove some bad genes just delete that row with it in my case i just delete row with Slow Learner Gene, keep in mind that this affect metabolism so my Neanderthals are now at 1.0 metabolism instead of 0.8.
Also keep in mind if game get new update it overwrites files which you changed so you had to change them again.

If you have hussar or access to unstoppable gene, you can make a rabbit for raiders to chase around.
Edit: wrong thread, oopsie

Yes. The same way they Jurassic Park'd the megasloth back. There's a dang rat that naturally produces chemfuel; get with the program!

Brought back from extinction even though nobody asked for it, because we can.
