The evolutionary advantage of recombination. II. Individual selection for recombination.
Based on the FISHER-MULLER theory of the evolution of recombination, an argument can be constructed predicting that a recessive allele favoring recombination will be favored, if there are either favorable or deleterious mutants occurring at other loci. In this case there is no clear distinction between individual and group selection. Computer simulation of populations segregating for recessive ...
متن کاملThe evolutionary advantage of recombination.
The controversy over the evolutionary advantage of recombination initially discovered by Fisher and by Muller is reviewed. Those authors whose models had finite-population effects found an advantage of recombination, and those whose models had infinite populations found none. The advantage of recombination is that it breaks down random linkage disequilibrium generated by genetic drift. Hill and...
متن کاملOn the evolutionary advantage of fitness-associated recombination.
The adaptive value of recombination remains something of a puzzle. One of the basic problems is that recombination not only creates new and advantageous genetic combinations, but also breaks down existing good ones. A negative correlation between the fitness of an individual and its recombination rate would result in prolonged integrity of fitter genetic combinations while enabling less fit one...
متن کاملEvolutionary advantage via common action of recombination and neutrality.
We investigate evolution models with recombination and neutrality. We consider the Crow-Kimura (parallel) mutation-selection model with the neutral fitness landscape, in which there is a central peak with high fitness A, and some of 1-point mutants have the same high fitness A, while the fitness of other sequences is 0. We find that the effect of recombination and neutrality depends on the conc...
متن کاملUnravelling the evolutionary advantage of sex: a commentary on 'Mutation-selection balance and the evolutionary advantage of sex and recombination' by Brian Charlesworth.
Delving into the literature on the evolution of sex is like picking up a dusty, old, unpromising book and discovering that a fascinating mystery novel lies within it. What makes this tome unpromising is that explaining the evolution of sex seems so trivial at first. Isn't it obvious that sex generates variation ? The fact that nearly all eukaryotes engage in sex, at least occasionally , reinfor...
