Genetica is a tool for using a simplified genetics system to generate inheritable traits for DnD characters.

You will need node and npm installed. Then run the command:

npm install -g genetica

genetica

Follow the prompts for Race and Gender (optional) and your DNA is outputted with information on traits.

Require genetica into your file and create a new Genetica class.

const Genetica = require('genetica');

const genetica = new Genetica();

const opts = {
  gender: 'female',
  race: 'Dragonborn'
};

const DNA = genetica.generate(opts);

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.
