Applications and Sexual Version of a Simple Model for Biological Ageing
We use a simple model for biological ageing to study the mortality of the
population, obtaining a good agreement with the Gompertz law. We also simulate
the same model on a square lattice, considering different strategies of
parental care. The results are in agreement with those obtained earlier with
the more complicated Penna model for biological ageing. Finally, we present the
sexual version of this simple model.Comment: For Int.J.Mod.Phys.C Dec. 2001; 11 pages including 6 fig
Bit-String Models for Parasex
We present different bit-string models of haploid asexual populations in
which individuals may exchange part of their genome with other individuals
(parasex) according to a given probability. We study the advantages of this
parasex concerning population sizes, genetic fitness and diversity. We find
that the exchange of genomes always improves these features.Comment: 12 pages including 7 figure
