HIP – Improved Genetics
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 attempts to make the genetics system a lot deeper. Traits can sometimes stay in your family for generations! Your spouse’s family traits are important! Inbreeding depression can actually be observed!
So how does it work?
The system is largely based on a simple model of Mendelian genetics. Every character in the game is assigned an allele pair for each trait (or several pairs for one 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.
I’m actually using 2 or 3 allele pairs for most traits, so the system has even more depth. No longer will you lose the genius trait in your bloodline just because your children didn’t inherit it! The high intelligence trait (quick or genius) will (most likely) persist in your bloodline! As of now the mod is not 100% complete, but it is an immense improvement on the base game’s genetic system. Do note, however, that for the sake of realism I have allowed a certain degree of randomness to remain, and so the improved genetic system might not be immediately noticeable.FAQ: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!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?This mod fires events for each character when they are born, so of course it slows the game down a bit. But, I didn’t notice more than a 5-10% drop in speed personally.Will this work without HIP?Just use the vanilla version of this mod! It doesn’t have the short trait, however.https://steamcommunity.com/sharedfiles/filedetails/?id=1518305370Can you describe in detail how this works?Check the discussions!——————–Non-steam download (version 0.5)https://www.dropbox.com/s/t2qbj209gkl2320/ImprovedGenetics.zip?dl=0
