Interesting comparison, after 1000 generations. (The previous examples used 20 genes. This is with 100 genes.)

Population = 100
Offspring per individual = 2.5
Recessive = 0
Average Fitness = 0.58


Average Fitness refers to average fitness of the children, so of 250 children, 58% have a fitness of one, more than enough to replenish the population of 100. The remaining 42% have a fitness of zero.

Population = 100
Offspring per individual = 2.5
Recessive = -0.001
Average Fitness = 0.98


The majority of children have a fitness between 0.993 and 0.999. Only a handful were stillborn.

Notice the large difference in average fitness due to the very slight effect of the recessive allele.
