Item Monte Carlo simulation of inherited longevity.(1999) Oliveira, Paulo Murilo Castro de; Oliveira, Suzana Maria Moss de; Bernardes, Américo Tristão; Stauffer, DietrichWithin the Penna model of biological ageing, we show that longevity is heritable, for both sexual and asexual reproduction.Item Simulating inbreeding depression through the mutation accumulation theory.(2000) Sousa, Adriano de Oliveira; Oliveira, Suzana Maria Moss de; Bernardes, Américo TristãoUsing the Penna model for biological aging, which is based on the mutation accumulation theory, we show that the number of homozygous loci corresponding to deleterious mutations is higher in small populations than in large ones. This decrease of heterozygosity may drive small populations to extinction even when no drastic change of the environment occurs.
