Improved Genetics 2.0

This mod improves the CK2 genetic system. As the title says.

This is the second version of the mod. The main reason for the reupload is that I lost access to the first mod even though it is mine (thanks Paradox!) To ensure continuing support, I've decided to reupload it.

However, there are some other changes:

• Fewer bugs
  
• Characters now get the new traits upon startup
  
• New traits now have better icons
  
• A new decision that lets you normalize your genes.

Do note that if you plan to use this with the old Improved Genetics, that is perfectly fine. However, you will need to fetch your save file from the 'gene' directory. I would advise finishing your save file before changing to this mod.

If for some reason this mod isnt working for you, check the old version: https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=1518305370


---------------------------------------------------------------------

CK2s genetics system is not very fleshed out at all. You can only inherit traits from your parents, and if you don't inherit them you lose the traits, for good. A lot of the traits genetic traits are mostly random, rather than persisting through your bloodlines.

This mod radically improves the Genetics system!

How does it work?

The system is largely based on a simple model of Mendelian genetics. Every character in the game is assigned allele pairs for each trait. When two characters have a child, the gene the child inherits is determined by a simple Punnett Square.



For example, a dwarf character might have an aa gene (recessive) and a normal character might have Aa (a carrier.) Their child then has a 50% chance to get the dwarfism gene. But even if they don't, they still have a chance of becoming a carrier.

The system is even deeper because each trait has 3 allele pairs associated with it.

Some trait inheritance is modeled through polygene inheritance, like the following graph for height:



In addition, this mod adds several new traits in the 4 polygene groups (intelligence, height, attractiveness, and strength.) These traits [dim, bright, delicate, sturdy, short (as opposed to tiny), tall (as opposed to giant), comely and homely] are weaker versions of vanilla traits and serve to really showcase the genetic system. These lower tier traits each have a 7% rarity (meaning 7 in 100 characters will have them.) Other rarities have been kept at vanilla levels for the most part.

My two genius characters did not produce any quick or genius children! What happened?

First, a character may get a certain GENE without getting that TRAIT. There is a genotype to phenotype conversion chance in this mod, determined by the number of dominant (or recessive pairs, for negative traits) alleles. So you may have the genius gene but not become a genius. Additionally, two geniuses may not pass down the genius gene, although it's unlikely. In general, the more rare a trait, the more likely it will persist in your family line.


I'm seeing way too many/way too few characters of (this trait)!

I've done extensive testing as well as calculations to make sure that the occurrence of traits more or less matches the base game. Traits are perhaps a little more common (intentionally.) But nothing should stand out as too common or too rare. If that is the case report it here and I'll have a look! A polygene trait like genius should have the following distributions: 0.4-0.6%, 1.5-2%, 3.5-5% for traits genius, quick, and bright respectively.

This is the frequency that I have found in my playthrough.


What about incest? Does this mod simulate inbreeding depression?

Yes. Kind of. Very close kin incest in this mod ends up (eventually) being very bad, as there is a high likelihood that you will end up with recessive traits in many birth defect traits like hunchback and clubfoot. However, you can generally escape inbreeding depression in just one or two generations of marrying people from outside the close family.


Does this slow down the game considerably?

I didn't notice any significant slowdown, surprisingly.


I'm not noticing any difference with this mod

Be patient. It's a subtle mod.


I get negative traits too frequently! :(

The mod has been thoroughly tested and this is not the case. You can use this python script to check: https://www.dropbox.com/s/xcxfecn3syezo0o/searchsaves.py?dl=0

Sometimes your family might start with horrible genes. This is an unlikely but possible scenario. If you dont want this to happen, there is a decision that you can choose in the first 25 years called 'normalize your genes.' This is available after the birth of your first child, and it will remove all recessive genes from your character.


Is this ironman compatible?

Yes, but you won't get achievements.


----------------------------------------------

Any mods that modify the 00_traits file won't work properly with this mod. The game will still start, but you will not experience the genetic system as intended.

If your mod adds new traits, the new traits will use paradox's base genetic system of inheritance, not mine.

Any overhaul mod will likely NOT WORK properly with this mod. The only overhaul mod I will fully support is HIP, because I personally know the team that works there. If any other overhaul mod team would like to implement improved genetics, they can contact me and I will gladly do that for them. In the mean time, if anyone wants to use it, I have a guide for how to edit the mod to make it work with an overhaul mod.

( DO NOT USE WITH HIP FURRY 7, FURRY 7 has improved Genetics integrated in the base mod.)

Download the drop box version, and then remove the common/traits/newtraits.txt file
