And the whole thing is pretty convoluted, when the essence of the model could be captured simply by assigning a fitness to the genotype and then calculating the number of offspring. |
From much of this discussion, it's easy to see how many different ways there are to abstract an evolutionary process.
These are the primary attributes I've found in Mendel's Accountant:
* Population of Genotypes (genotypic fitness).
* Genotype modified by heritability and noise to Phenotype (phenotypic fitness).
* Genotype further modified for chance of reproductive success to Working Fitness.
* Number of offspring proportional to sqrt(Phenotype).
* Reproduction with mutation.
* Throw in more random factors, such as random death. |
No recombination? We know about mutational meltdown, and we also know that sex can mitigate the effect.

Don't ask Gil to help with the programming for that.
