The study analyzes the results for average population fitness over 10 generations produced by 4 different pairs of values for the parameters, degree of inbreeding and homozygote fitness. It demonstrates that the model works and that the self-recognition mechanism is most responsive when the threat to survival of the population is greatest. </p><p>Without the compatibility system, the proportion of homozygotes grows with inbreeding, and average population fitness plummets accordingly. The compatibility system reverses this trend. As inbreeding rises, more of these AA/aa homozygotes are eliminated through natural selection over time such that the increase in heterozygosity accelerates. Since the heterozygotes are the fittest among the genotypes, the decline in population fitness decelerates over time proportionate to the degree of inbreeding and the fitness of the homozygotes. This process manifests itself as nature responding to the level of emergency.</p> 2009-08-11 English text University of Cincinnati / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=ucin1243359525 http://rave.ohiolink.edu/etdc/view?acc_num=ucin1243359525 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
