Summary of nucleotide diversity within maize taxon or population.

a<p>Some sequence data were from Mason et al (1998), Gaut et al (2000); Whitt et al. (2002), Tian et al. (2006), and Zhao et al. (2008).</p>b<p><i>n</i>, number of samples; <i>S</i> : number of polymorphic (segregating) sites; <i>H</i>, haploid; <i>Hd</i>: haplotype (gene) diversity; <i>π</i>, The average pairwise nucleotide diversity (Tajima 1983); <i>θ</i>, an estimate of 4N_eμ, where N_e is the effective population size and μ is the mutation rate per nucleotide (Watterson 1975); <i>K</i>, average number of nucleotide differences; <i>D:</i> Tajima’s D (1989); <i>D*</i>:Fu and Li’s D (1993); <i>F*:</i> Fu and Li’s F (1993); <i>Rm:</i> Minimum number of recombination events.</p>**<p><i>P</i><0.01; * <i>P</i><0.05.
