Mean nucleotide diversity (π) is higher at S. cerevisiae centromeres (in CDEII) than in selectively unconstrained sequences (TEs)

Nucleotide diversity of CDEII (π) was estimated across the CDEII component of all 16 centromeres and π for TEs was estimated for the 210 loci at which TEs appeared fixed. P values are the result of Wilcoxon tests comparing 16 estimates of π of CDEII to 210 estimates of π of TEs for each population.
