Implication

Simulation study demonstrates that recombination breaks linkage disequilibrium caused by genetic drift, suggesting a mechanism for the persistence of sexual reproduction.

Key Points

To resolve theoretical discrepancies regarding the evolutionary benefit of recombination and evaluate whether finite-population effects explain its origin and maintenance.
Reviewed theoretical population genetics models comparing infinite-population assumptions to finite-population dynamics.
Linked the Fisher-Muller hypothesis to the Hill-Robertson effect and Muller's ratchet mechanism.
Conducted computer simulations of the substitution rates of beneficial mutations and the long-term accumulation of deleterious mutations.
Finite-population models demonstrated that recombination provides an advantage by breaking down random linkage disequilibrium generated by genetic drift.
Without recombination, linked loci interfered with one another's response to natural selection, even in the absence of direct gene interactions.
Computer simulations verified that recombination accelerates the fixation of favorable mutations and halts the progressive accumulation of deleterious mutations via Muller's ratchet.
