Genetics Trackers

Each wolf's family tree page has three genetic trackers, which display a brief but useful overview of the wolf's genes.

## Inbreeding Coefficient (COI)

Inbreeding coefficient, or COI, gives a quick and simple view of how heavily inbred a wolf is in its more immediate family. The COI rate is calculated by comparing both biological parents' family trees together. If the same wolf appears in both trees, then it affects the COI of the offspring. The common ancestors' COI rate also plays a part in the offspring's COI. Though, this calculator only goes as far back as the family tree is displayed on one page, and will ignore anything further than that.

However, if you breed an inbred wolf with another wolf that has no related ancestors to its partner, then the offspring's COI rate will be at 0%. This is because the COI rate only pays attention to if the two parents share a common ancestor, meaning that the same wolf appears in both of their lineages. Both parents could be heavily inbred, but as long as they share no common ancestors, their offsprings' COI will always be at 0%.

### A rough guide by the admins showing how COI is calculated

* 25% COI is equivalent to a parent x offspring breeding, or full sibling
* 12.5% COI is equivalent to a half-sibling pairing, or grandparent x grandchild breeding
* 6.25% COI is equivalent to a first cousins, or great grandparent x great grandchild breeding
* More than 25% would indicate there are multiple instances of inbreeding in the family tree, as it is cumulative as well

The maximum COI rate possible is still unknown, though is speculated to be 100%.

## Instances of Inbreeding

Instances of inbreeding displays the amount of times the same wolf appears in a lineage more than once. This tracker only goes as far as the family tree is displayed on the page, and will only count the instances that can be seen.

Wolves with duplicate ancestors are commonly referred to as IB (inbred), while ones without are referred to as NIB (not inbred). NIB wolves are typically more valuable on the market, as many players may find inbreeding disturbing, or just want to challenge themselves with housing only NIB wolves. However, inbreeding currently has no effect on gameplay.

## Generation

A wolf's generation is counting how far back its lineage goes. All wolves without parents, such as NBWs (new befriended wolves), will have their generation display Gen 1. Assuming two parentless, or Gen 1, wolves had pups, then the pups' generation counter will display as Gen 2, and their offspring will become Gen 3, and so on. Unlike the COI or the Instances of Inbreeding counters, the Generation tracker goes way back to the farthest parts of the lineage, and isn't limited to what's shown on one family tree display page.

However, some wolves with chased or destroyed records of an ancestor may not get the correct readings in their generation tracker, so players will have to go and manually count the ancestors. Though the admins implied that this should be fixed with newer wolves.

When the update first came out (10 June, 2022), most of the wolves on the site had an unknown generation in their tracker. This was most likely due to the update still being very recent and not having enough time to calculate every wolf’s generation, especially ones with long lineages. It was fixed upon the next rollover, though.
