Uniform vertical transmission and selection in a host-symbiont system. Non-random symbiont distribution generates apparent differential selection.

Abstract excerpt

We investigate the survival, prevalence, and distribution of a symbiont in its host population when the forces of vertical transmission (beta) and symbiont-induced selection (s) are uniform (invariant across host genotypes). We use host-symbiont disequilibria to quantify the role played by non-random associations between host genotypes and the symbiont in altering host genetic structure. Results show a larger...
