MK test significant regions.

Target regions with most significant p-values for McDonald-Kreitman-like test distinguishing the fixed substitutions on the chimp or human lineage from the mutations at segregating sites, comparing weak-to-strong and strong-to-weak mutations. Starred regions are also significant in the MWU test (Table 1). S2W indicates that the fixed differences are biased in the direction of strong-to-weak mutations. Other headings as in Table 1. Starred telo values are measured from the chromosome 2 fusion of ancestral telomeres presumed at human chr2:q14.1.
