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.

You may as well throw in another factor that randomizes falling off a cliff and whether she has a headache,

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

It is fun to dip into the various threads to watch cluelessness at work in the hands of the confident exponent. - Soapy Sam (so say we all)
