# genetica
Genetica is a tool for using a simplified genetics system to generate inheritable traits for DnD characters.
[](https://nodei.co/npm/genetica/)
[](https://travis-ci.org/opendnd/genetica)
## Installation
You will need [node](https://nodejs.org/en/) and [npm](https://www.npmjs.com/) installed. Then run the command:
`npm install -g genetica`
## Generate DNA from CLI
```shell
genetica
```
Follow the prompts for Race and Gender (optional) and your DNA is outputted with information on traits.
## Module Usage
Require genetica into your file and create a new Genetica class.
```javascript
const Genetica = require('genetica');
const genetica = new Genetica();
const opts = {
gender: 'female',
race: 'Dragonborn'
};
const DNA = genetica.generate(opts);
```
## Simplified DNA System
Each generated character has a set of DNA with chromosomes. These chromosomes go to applying traits.
Each chromosome has two pairs with dice rolls based on the size of the chromosome: either `d2`, `d4`, `d6`, `d8`, `d12`, `d20`, or `d100`. So for example, Chromosome 1 has a size of `d8` and the pair rolls for `5=8` which means the mother gave a roll of `5` and the father gave a roll of `8`.
__Rules__
- Dominant/Recessive Genetic Rules: A rule of `3` means if 3 is the highest rolled then the trait applies. For example: a chromosome pair of `1=3` would mean the rule applies as 3 is the highest roll, but for a pair of `8=3` it would not.
- Co-dominant Genetic Rules: `1=3` means that the roll for the mother must be 1 and the father must be 3 in that order. A `3=1` would not apply the rule. ___This rule is checked BEFORE the dominant/recessive rules___.
