This package provides functionality for simulating genetic inheritance in creatures using Mendelian inheritance principles. It facilitates the creation of genes, genotypes, and creatures with customizable genetic properties.

Installation

You can install the package via npm:

yarn add mendelian

Usage

Creating a new seeded Genetics instance

import { Genetics } from "mendelian";

const genetics = new Genetics({ seed: "idrinkandiknowthings" });

Creating Genes

const blueEye = genetics.createAllele({
  trait: "eye-color",
  dominance: 3,
  description: "blue",
});

const greenEye = genetics.createAllele({
  trait: "eye-color",
  dominance: 5,
  description: "green",
});

const brownEye = genetics.createAllele({
  trait: "eye-color",
  dominance: 8,
  description: "brown",
});

Creating Creatures with Genes

const creatureOne = genetics.createCreature({
  genes: {
    eye: genetics.createGene({
      trait: "eye-color",
      alleles: [brownEye, blueEye],
    }),
  },
});

const creatureTwo = genetics.createCreature({
  genes: {
    eye: genetics.createGene({
      trait: "eye-color",
      alleles: [brownEye, blueEye],
    }),
  },
});

Reproducing a child

console.log(creatureOne.mate(creatureTwo).genes.eye.phenotype.description); // => brown
