mendel.py: A basic genetics package

mendel.py is a simple system to play with the genetics of inheritance in a very simple and user-friendly manner.

It is written with a functional approach to genetics, with a creature definition being "compiled" to a bunch of functions that operate on "genomes", which are simple strings.

How to use

self_test.py showsa simple example of a creature template, and the 3 functions the compile_creature() returns.

In principle, all tests start with a template. The template defines certain traits, that are identified with a allese letter, that is capital for dominant and small for resessive. Support for co-domiance is not added yet.

Templates are dictionaries:

template = {
    "trait A" : {
        "type": "mendel",
        "letter": "A",
        "dom": "A expresses"
        "res": "A not express"
    }
}

The above template tracks a trait A, which has 2 alleles, A and a.

For a genotype "Aa", the trait expresses will be "A expresses"

The compile_creature function returns 3 functions:

1. A express function: returns a list of expressed traits for a given genotype
2. A check fucntion: Checks to see of genotype is valid
3. A cross function: Returns all offspring of a cross between 2 genotypes
