Genetic diversity in asexually reproducing populations of the semelparous Penna model

We quantify the diversity of populations simulated using the Penna model with an entropy of genetic diversity measure by Pan et al. When selection is removed by increasing the resistance to disease, populations result to a zero-steady state diversity. While for cases with selection, greater genetic diversity was achieved by delaying reproduction. It was also found that populations with genetic diversity tend to have increased average lifespan and resilience to epidemics.
