Tables

• Supplementary Table 1.     GC content is elevated in primate X palindrome arms relative to flanking sequence. P-values are from chi-square test with Yates correction.
• Supplementary Table 2.     GenBank accession numbers for chimpanzee and rhesus macaque clones analyzed for this project.

Figures

• Supplementary Figure 1.     Fraction GC content for simulated palindrome arms and ancestral sequence. Magnitude of GC bias = 0.70, starting GC content = 0.40. Each dot (n=100 for each category) represents median GC content for a set of 12 simulated palindromes. ****p<0.0001, Mann-Whitney U.
