It should be. I wonder how they calculate it, though. The description makes it look like they calculate the genotypic variation in fitness, and then multiply it by 4 to get the environmental variance, and create a random environmental effect for each individual with that variance. But that's nuts, because it means that the amount of environmental variation in fitness is directly tied to the amount of genetic variation.
it's possible, though, that they're doing nothing like this: the description is rather confused.
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)
