Picture #006 We survived, but the wanderer died from old age. Eplway had a fourth child, but he or she died after birth. This is likely because Eplway and Oqudhe have one of the same immunities, either A or B.

Picture #005 I got carried away. Hopefully we'll survive this. The Bearyena is just hanging out on the left. So far, we're living in peace. For now.

Picture #004 The second child, Eplfaylun, and her younger sister, Nniepl.

Picture #003 The first son, Uckju, finds a 63-year-old Wanderer, Yepuphudwyu. (A mouthful, I know.)

Picture #002 Eplway found herself a hubby.

Giving this a shot, even though it's been several years since this challenge came out. Used the sandbox settings. Will be posting any cuties that are birthed or that I invite into my tribe. Original rules:

I'll give it a shot

Are you going to continue this lineage @Lizardcake? It's quite cool to see the phenotypic and genotypic change of your patriarchy.

The terms I use most often that have to do with Niche are: Nicheling: The player-controlled animals in your tribe, as well as wandering animals, prehistorical animals, and rogues males. Hybrid: Player Animals that are a result of mating between a Nicheling and Bearyena. Blue Bird: The bird of prey that kills Nicheling babies and young (1 gem) Nichelings. Save File: A file located in the Niche game Library in the hard drive that contains your precious game save. Carnivore: Used to mention any predatory enemy animals, especially Bearyenas. "Sacrifice [Nicheling name] to the Water Gods": A euphemism for drowning (killing) a Nicheling you don't want anymore. Adam: The male Nicheling you start with in Story Mode Gems: The 1 to 3 colourful dots on your Nicheling's chest that indicate how many action points your Nicheling has left for the day [the old name for rogue males]: REDACTED Is anyone here from the time where Rogue Males were called something else? 😹 That was funny.

I was able to change genes on a save with only one PlayerAnimal! I did this in a Story Mode file with Eve as the "birth parent". Editted. It's kind of a "dead fish eye" kind of blue. The lack of light reflection (white specks) on the eye might change how it looks. Also, it might have a bit of green, so it's more teal? The closest colour is still definitely blue.

Introduction: There is a famous Niche bug that occurs when a pregnancy is induced by console commands. This full-grown headless Nicheling entity appears in the nest and causes the save file to be unusable, that is to say the game cannot be exited, and any attempts to use the save file result in a Hedgehog-Day phenomenon where the save starts the day the Dullahan was born. I shall use the terminology Dullahan to describe what are know as “Headless Ghosts”, “Demonspawn”, "Pregnancy Demons", and “Headless Monsters” (see sources below). A "Dullahan" is a headless horseman who carries his own head (from Irish folklore, see Wikipedia). Past sources: https://steamcommunity.com/app/440650/discussions/1/2549465882933982450/ https://strayfawnstudio.com/community/index.php?/topic/10818-activatestatuseffect-pregnant-glitch/ https://strayfawnstudio.com/community/index.php?/topic/3197-console/ (Post by Goggles-kun, Glitch #8) Note that the last source shows Dullahans with a different phenotype than more recent Dullahans. Credit goes to Modiano (a.k.a. Golden Fawn) for discovering how to manually "debug" this bug. I have compiled a procedure on how to seemingly circumvent this bug based on my own experience with this workaround. (Golden Fawn's original post: Important Notes: - Do not try to exit the game until mentioned in the steps. - The sex (male or female) of the Dullahan seems to be determined at random. - This is not an easy glitch to work around. Not suitable for those who are unfamiliar with console commands. Methodology: 1. Open the console commands and use “addstatuseffect pregnant” on the Nicheling of your choice. Note that if you choose a female Nicheling, she must have not mated before. 2. Set the pregnant Nicheling on a nest and pass the day. The Dullahan should appear. 3. Open the console commands and “increaseage 1” on the Dullahan. 4. With the console, set all the gene slots with the “setgene …” command. That is, ears, horns, eyes, etc. (Note: the command will not disappear as it usually does, but it is making an effect. I recommend to press enter twice to ensure that it has been entered.) Troubleshooting: if the Dullahan doesn’t change appearance (into whatever genes you’ve set), you have missed a gene. 5. (Read this whole step before attempting) After completely setting the genes of all your Dullahans (who should appear normal by this point) you can either pass the day and then quit/exit, or just quit/exit the game. Once the game has frozen (yes, it will freeze) and you exit Niche, the save file should have updated. 6. Start Niche again and play the same save that had froze. 7. Your PlayerAnimal should be a fully-functioning one-year old. Now you can increase it’s age to 6 (adult) with the “increase age 5” command or whatever you like (change it's name, it's genes, it's mutation menu, etc.) Now that you’re done, you should be able to play the save file as normal. You can leave the island and leave the game, both without any repercussions. However, the PlayerAnimal will not show who the parents are, not even the birth parent. Attached are photos of what the Dullahans look like (in the current version), and what genes the Dullahans might have based on their phenotype (Image 1 & 2 below). Note that the Dullahan seems to have blue eyes (in Image 1), despite it seemingly being recessive for (having two copies of) the albinism gene. In a future experiment, I might see if this also works for the "ActivateStatusEffect Pregnant" command. If anyone who reads this is able to salvage their corrupted saves from previous versions, or if there are issues with this guide, please let me know in the comments!

Has anyone else noticed that the pattern shape genes have this kind of pattern?

Yes, I also found that round ears prevail over both due to maternal inheritance. I took another look at my notes and medium ears are always dominant over big ears. Glad to know there are others who are interested in this stuff haha

Fraternal twins 😄 They're a bit funny-lookin' cute!

It’s possible that there is a bigger glitch with the hemophilia gene in Niche - a genetics survival game. When crossing females that are carriers for the hemophilia gene (they only have one copy of the gene) with males with normal blood clotting, I was surprised to find that I never seemed to get sons with hemophilia. To determine if there was probably an issue with this, and to determine that it was not just due to RNG, I carried out three simultaneous crosses in a game file. Those three crosses yielded: #1, 16 males and 16 females; #2, 14 males and 16 females; and #3, 11 males and 6 females. Of those crosses, I obtained: #1, only 9 females carriers; #2, only 4 female carriers; and #3, only 4 female carriers. Based on Mendelian genetics, and because the male has normal blood clotting and the female is a carrier, there should be a 1:1:1:1 ratio of all four genotypes among their offspring, i.e., 1/4 hemophilic males, 1/4 normal males, 1/4 carrier females, and 1/4 normal females. In this experiment, we have 79 young Nichelings; 38 females and 41 males. Half of the offspring should be either male or female, so a ratio of 41 to 38 is reasonable, even without statistical testing. We do, however, have only 17 carrier females of hemophilia, and 0 hemophilic males. Compared to the total female count of 38, 17 carrier females is approximately 44.7% of that amount. A Chi-squared test may determine whether 44.7% is statistically different from 50% (the expected value), but because the sample size is only 79 the statistics don’t carry enough weight. To have a more accurate statistical measure, a sample size of 1000 would be best, but this is not reasonable for a single save file in Niche. What I can say is that there should be around 20 hemophilic males across my three crosses, i.e., half of the 41 males, and yet they are missing. My theories are that: 1) there is a glitch where sons only inherent the father’s blood clotting and no gene (Y gene); or 2) there is a glitch that converts the mother’s hemophilia gene to a normal-blood-clotting gene. Either way, in the current version of the game, it is seemly impossible to obtain a pure-breeding hemophilia Nicheling population due to this. If you cross a hemophilic male with a hemophilic female or a hemophilic male with a heterozygous female then you do get all four genotypes (General Feedback/Bug post, Robb Plat), which seems to indicate a glitch with inheriting the father’s genetics. What does that mean for the typical Niche player? Hemophilic males are impossible to breed via either a carrier female or hemophilic female (General Feedback/Bug post, Robb Plat), so it’s impossible to get males and females with hemophilia in your games now, unless you put it in your mutation menu. At least you can outbreed with wandering Nichelings that have hemophilia without too much concern that it will proliferate in your population, assuming your population doesn’t already have hemophilia. (Image below shows my test population. Note that no individuals express hemophilia due to this glitch, except for Komiana who is a wandering female.) Robb Plat Diploma in “Biolology”

You're welcome! I believe this also occurs with medium ears and round ears, and medium ears and big ears, but I have yet to fully experiment on these. In an old version, there was a strange occurrence with gills and big nose, but that has since disappeared and big nose is now dominant to gills.

Mendelian dominant and recessive genes, and sex-linked genes are the bread and butter of Niche - a genetic survival game. However, there some unusual game mechanics that result in strange modes of inheritance. In particular: the purple and yellow eye colour genes, the round and big ear genes, and the hemophilia and normal blood clotting genes. Using a reciprocal cross of male and female Nichelings, I determined that the eye colour and ear genes are based on whether the gene was passed down to the offspring from the mother. The hemophilia gene, however, was only passed down if the father was also a hemophiliac. Only the developers know whether these are intentional or unintentional modes of inheritance. I created two sets of Nichelings: #1) one wherein the mother had big ears and purple eyes, and #2) the other wherein the mother had round ears and yellow eyes. The fathers had round ears and yellow eyes, and big ears and purple eyes, respectively. Once crossed, cross #1 only resulted in offspring that had big ears and purple eyes, whereas cross #2 only resulted in offspring with round ears and yellow eyes. Each couple had about 20 children. I conducted this experiment in three separate game files. I assumed that there were no linked genes and that a pure-breeding population was not necessary for this experiment. The mutation menu was not used. We also conducted an F2 test cross in the same file, wherein the mothers were heterozygous for both ear and eye colour genes, and the fathers were homozygous for both genes. Again, we find that if the mother passes the gene to her children, it will be expressed as the dominant gene, whereas the same genes in the other reciprocal cross were recessive. I find this is strong evidence to support my theory that the purple and yellow eye colour genes, and the big around ear genes are based on a “maternal mode of inheritance.” This mode of inheritance results in the heterozygous offspring having an appearance more like the mother, i.e., the dominant ear and eye colour genes are always from the mother. I am not sure if this mode of inheritance is based on something that occurs in real life, but it occurs in this game. In a separate experiment, I crossed two sets of Nichelings: #1) one wherein both the mother and father are hemophilic, and #2) the other wherein only the mother is hemophilic. As this was an issue I encountered in the past (See Hemophilic Female, in Bug Reports, Robb Plat), I was fairly sure of the outcome. The first cross between hemophilic parents resulted in hemophilic children. This should be expected. Cross #2, however, showed something surprising… the male children from this cross all had normal blood clotting! This result was the same as my previous statement (Hemophilic Female, in Bug Reports, Robb Plat), wherein a hemophilic female had sons with normal blood clotting. In normal sex-linked genes, the sons get their Y chromosome (or in Niche, the “no gene”) that makes them “male”. Likewise, they get one blood-clotting gene from their mother, and in the case of the mother with two hemophilia genes, he should only get the hemophilia gene. However, we see that he appears to inherent both of his father’s blood-clotting genes, or the normal blood clotting gene comes out of nowhere! I gathered females that were heterozygous for the blood-clotting genes from cross #2 and crossed them to males with either #1) normal blood clotting, or #2) hemophilia. We found that this game mechanic worked normally, as we obtained female carriers of hemophilia, and normal offspring from cross #1, and hemophilic and normal males and females from cross #2. Unfortunately, I didn’t get any hemophilic males from cross #1 (which is not expected from a heterozygous mother), which I assume to be due to the power of RNG. Additionally, I crossed third-generation hemophilic female and normal-blood-clotting male (from the same game file). Again, we found that the male offspring had normal-blood clotting, as if from thin air. The first image below shows Lame, whose mate (Dukkudon) has normal-blood clotting, and her children. Based on the male/female names, you can see that the daughters are all carriers for hemophilia and the sons are healthy. In real life X-linked genetics, the sons should actually be hemophiliacs. Robb Plat, Dipolma in “Biolology” Supplementary photos: The second and third images below show Ella, Lame’s younger sister, and Rata, their cousin. Ella and Rata are both homozygous for yellow and purple eye colour genes, respectively. The family tree shows that all of Ella’s children have the purple eyes as their recessive gene, whereas Rata’s children have recessive yellow eyes. Ella’s mate (Dukpri) is homozygous for purple eyes, and Rata’s mate (Takirpri) is homozygous for yellow eyes. Also note that Lame has big ears with round ears recessive, and Rata has round ears with big ears recessive. They inherited the dominant gene from their mother. Dukkudon’s genetics are shown in the fourth image.

Naturally I'll be taking on my own challenge too. Got some cute twins from the get go.

Bearyenas and wanderers/rogues will be gone as there are only 6 Nichelings left.

parent and child and siblings would be not allowed, but other others you mentioned are fine since it's a small population.

I have questions about this. Firstly, immunity genes cannot be mutated. Secondly, if the baby Nicheling is sick due to double immunities, then likely the parents just have an immunity gene or two in common.

I may post more if there's any interest, like the save file to start with.
