  • N-derived are sites at which the Neanderthal has a different nucleotide than in the chimpanzee sequence (n = 177); N-derived (CpG) are N-derived sites at which the human SNP is in a CpG pair (n = 24); N-ancestral are sites at which the Neanderthal and chimpanzee have the same nucleotide (n = 461); N-ancestral (CpG) are the N-ancestral sites at which the human SNP is in a CpG pair (n = 84).
