Simulating Male Selfish Strategy in Reproduction Dispute
We introduce into the Penna Model for biological ageing one of the possible
male mechanisms used to maximize the ability of their sperm to compete with
sperm from other males. Such a selfish mechanism increases the male
reproduction success but may decrease the survival probability of the whole
female population, depending on how it acts. We also find a dynamic phase
transition induced by the existence of an absorbing state where no selfish
males survive.Comment: 7 pages, latex including 2 eps figure
