I had something strange happen. I had 2 courtiers with genius marry and I granted them a title. Some years later I checked in on them and they had 7 kids, all with the "quick" trait, not a single genius child. Just think something might off in this mods calculations for child traits in other courts besides your own. Perhaps something that happens randomly, most families I put together like this have random traits. This one was just... weird.

That improved genetics mod is actually kinda bad. Gonna try this and hopefully will be less garbage characters/children in the game.

Come back and combine this mod with improved genetics and continue it. OP of that is gone. ''Huge fan of genetics and EpiGenetics. Want to breed a long family line of strong genes and traits I want like Left Handed and Tall. You should also make this take stats into account. Where 2 high stat parents will pass on those high stats from birth and better stat gains for their high stat skills. Make it so it counts base stats as full. But only half or 1/4 bonus from bonus stats. Please do it.

So, to be clear.

If one or both parents are geniuses... there's a chance their children might pick the trait up too.

It doesn't do what the other genetics mod does, right? (I found that kind of ridiculous - the guy overthought it all based on one fact about genetics he found out lol)

Yes I think it just adds new txts with traits, couldn't find those files using search in mod folder (they are all extracted).
Thanks for the mod!

If Dark World doesn't change traits_00 or traits_02 then yes.
B flat Jul 13, 2019 @ 7:48am 
So I guess this should be compatible with Dark World?
John Jun 29, 2019 @ 10:40am 
Thank you for the mod :)
water  [author] May 20, 2019 @ 3:46pm 
I'm almost certain that you can't.
CrimsonKing May 19, 2019 @ 9:23pm 
Is your mod compatible with Improved Genetics 2.0? Can I use both of them at once? Maybe someone already checked
water  [author] May 19, 2019 @ 6:23pm 
No. The author of that is using an actual genetics model whereas this mod simply increases the chance that congenital traits will be based down if both parents have the trait.
CrimsonKing May 19, 2019 @ 10:39am 
Is your mod the same as Improved Genetics 2.0?
プロメスティン May 13, 2019 @ 12:35pm 
yeah, it seems to have fixed the issue, thanks fam.
water  [author] May 13, 2019 @ 4:23am 
Okay after some headache there trying to figure out how to get it updated on my new computer, it should be working. Let me know if there's still an issue.

But even without any of those mods, just this alone was enough to block me from hellenic
プロメスティン May 13, 2019 @ 2:04am 
Yes, a fuckload of them, but none except for eugenics blocks me from Hellenism regardless of what combination of mods I use.

water  [author] May 12, 2019 @ 11:45pm 
Totally not a sperg, do you have any mods enabled that change decisions or events? I don't see anything that should impact the delve into the classics decision.
Throsky May 12, 2019 @ 9:14pm 
The 2nd way to restore Hellenism[More just that you secretly convert it to this way] is that you need to have the scholarly focus+ Lunatic .
water  [author] May 12, 2019 @ 8:51pm 
Huh, I'll give the traits file a look and see what I can find. Is there some trait you need for Hellenism? I didn't think there was.
プロメスティン May 12, 2019 @ 4:02pm 
I'm not sure if you are aware of this, or if you care for that matter.
But your mod seems to block Hellenism and Hellenic reformation.
water  [author] Dec 17, 2018 @ 1:59pm 
I'm not sure what you mean by tribal cultures. This mod only impacts traits.
Vindur Dec 16, 2018 @ 7:54pm 
Is the update for holy fury supposed to work with tribal cultures as well? It doesn't seem to work for me or my friends at all while we play scandinavians. :steamsad:
leonnolan Jul 28, 2018 @ 12:34am 
Wow. There are people who are actually complaining about the name of this mod? A Crusader Kings 2 mod, where you literally practice eugenics in the base game in order to get desired traits in offspring, by selecting who can breed and who can't? That really takes some doing.. xD

Anyway, great mod. I hate having all my good traits just disappearing in offspring. Even cousin marriage won't often save them. -_-
Throsky May 15, 2018 @ 4:03pm 
It depends. With one parent having Genius, it's vanilla chance. With both parents having it, I believe it's doubled of vanilla.
Omniburg May 15, 2018 @ 2:25pm 
So what are my odds of passing down genius with this mod enabled?
Johann van Buren Feb 26, 2018 @ 8:30am 
This mod in conjunction with Sketchy Traits will vastly increase 'Low Fertility' being passed on, as well as fertile, resilient, well-endowed, etc. Great mod, does what it says!
메타매직 Jan 24, 2018 @ 1:34pm 
Awesome mod!
Candlefire Dec 25, 2017 @ 11:39am 
I figured, thanks!
water  [author] Dec 22, 2017 @ 3:02am 
Should be, but it won't retroactively do anything. It'll change the chances of children born once you have the mod.
Candlefire Dec 21, 2017 @ 5:54pm 
save compatable?
Faenus Nov 8, 2017 @ 6:24pm 
@bfel001 then stop complaining about it and just make it yourself if it bugs you so much
bfel001 Nov 6, 2017 @ 5:12am 
WELP, one more "eugenics" mod that doesn't do what I hoped. Every time I see one of these I think someone finally made base attribute scores pass down instead of being trait based and every time I'm disappointed.

So I guess I just have to keep posting this on every single one of these that pops up till it finally happens.
ComradeConman Oct 17, 2017 @ 7:39am 
finally i can have weak, frail, inbred imbeciles thanks author. P.S no catalonia thanks anyway
water  [author] Sep 29, 2017 @ 11:39am 
No, it doesn't.
Rene2410 Sep 27, 2017 @ 11:28am 
does this mod cause Low fertility -30% ? I got so many people around world with this trait
water  [author] Sep 19, 2017 @ 2:53am 
It should if ck2+ doesn't change the traits file.
PC_Principal Sep 19, 2017 @ 2:41am 
Hey there, great mod but does it work with CK2+?
Shanawa Sep 13, 2017 @ 6:48am 
Just checked again it was a custom char, so who knows if i might have ticked inbred on by accident. He wasn't inbred, so I guess i was just REALLY unlucky lol.
water  [author] Sep 12, 2017 @ 6:05pm 
There is no base chance to get inbred. Was your character inbred? If so, you just got unlucky; which happens in small sample sizes.
Shanawa Sep 12, 2017 @ 5:57pm 
Uhm okay, so the thing is, which reminded me that i've tried this mod before. There is way too big a chance of your children being "inbred" I had 10 children, 6 male, of them 4 was inbred, I had 4 girls, of them none was inbred, which i found odd, furthermore it was only the children I had gotten through seduction that were inbred, even though they werent related to my dynasty, I don't know how much of these facts are related to each other..
Shanawa Sep 12, 2017 @ 4:27pm 
The buff dosn't sound like a bad idea, it really is a weak trait at the moment.
Kelarra Sep 12, 2017 @ 12:18pm 
does this work with the hip mod ?
water  [author] Sep 10, 2017 @ 8:45am 
I'm not sure how you guys would feel about this (which is why I'm asking), but I felt like buffing the attractive trait only made sense considering how much worse it is than even strong. I was thinking I'd add some diplomacy to attractive (1 or 2), split the attraction opinion into +10 vassal opinion and +20 attraction opinion and then move the +10% fertility from strong to attractive (I imagine you're more likely to have sex if you're attractive, but that could just be speculation).

Let me know what you think.
Soshmal Sep 9, 2017 @ 4:33am 
Yes.
water  [author] Sep 9, 2017 @ 2:15am 
Had you played republics in multiplayer in the past with no issues?
Soshmal Sep 8, 2017 @ 1:33pm 
Me and my friend tried this mod out in multiplayer, and (as a republic) we encountered a glitch where each others decisions affected the others game.
Abelardo Aug 29, 2017 @ 10:35am 
@sillysam22: You have to go back to the next page to know why the fuss about "Nazi" is here. >^^<
SillySam22 Aug 29, 2017 @ 1:17am 
@raven8775 What's the problem with that ?
Tibby Aug 28, 2017 @ 5:53pm 
Guys you can stop virtue signalling about how anti-SJW you are. The mod creator already handled it. The word can cause problems but the mod creator explained why it isn't problematic, problem solved. Further talk of SJW's is pure virtue signalling.
Rene2410 Aug 28, 2017 @ 2:25pm 
thank you creator for manual download
