Evolution and Selection of Quantitative Traits

This chapter examines the relative strengths of the nonadaptive evolutionary forces (drift, mutation, recombination) acting on genomes. It reviews estimators for effective population size, mutation rate, and recombination rate, and summarizes the known genomic results over a wide range of taxa. The mutation rate tends to be lower in organisms with larger effective population sizes, consistent with the drift-barrier hypothesis wherein selection is ineffective when it is less than the reciprocal of the effective population size.

Keywords:   codon bias, drift-barrier hypothesis, four-allele test, Lewontin's paradox of variation, Luria-Delbruck distribution, nucleotide diversity, number of segregating sites, Tajima estimator, Watterson estimator
