The first six characters of an item name show the status of the allele (A, D or _ if not known) in six genomes: human reference, San, Yoruba, Han, Papuan, and French, in that order. These characters are followed by a colon, the number of derived alleles found in Neandertals, a comma and the number of ancestral alleles found in Neandertals. For example, a SNP labeled AAADAA:0D,2A has the ancestral allele in the reference human genome and in all of the modern human genomes except Han. Among Neandertals, two instances of the ancestral allele were found, but no instances of the derived allele. </P> <P> SNPs are colored <B><FONT COLOR = "red">red</FONT></B> when at least four of the six modern human genomes are derived while all observed Neandertal alleles are ancestral. An overrepresentation of such SNPs in a region would imply that the region had undergone positive selection in the modern human lineage since divergence from Neandertals; the <A HREF="/cgi-bin/hgTrackUi?&c=chr1&g=ntSssZScorePMVar">Sel Swp Scan (S)</A> track displays a signal calculated from these SNPs, and the <A HREF="/cgi-bin/hgTrackUi?&c=chr1&g=ntSssTop5p">5% Lowest S</A> track contains the regions in which the signal most strongly indicates selective pressure on the modern human lineage. </P> <H2>Display Conventions and Configuration</H2> <P> <B><FONT COLOR = "red">Red</FONT></B> SNPs are those where at least four of the six modern human genomes are derived while all observed Neandertal alleles are ancestral.

SNPs at CpG sites were excluded because of the higher mutation rate at CpG sites. Ancestral or derived state was determined by comparison with the chimpanzee genome. </P> <H2>Credits</H2> <P> This track was produced at UCSC using data generated by <A HREF="mailto:ed@soe.ucsc.edu" title="ed@soe.ucsc.edu" rel="nofollow" TARGET = _BLANK>Ed Green</A>. </P> <H2>Reference</H2> <p> Green RE, Krause J, Briggs AW, Maricic T, Stenzel U, Kircher M, Patterson N, Li H, Zhai W, Fritz MH <em>et al</em>. -<a href="http://science.sciencemag.org/content/328/5979/710" target="_blank"> +<a href="https://science.sciencemag.org/content/328/5979/710" target="_blank"> A draft sequence of the Neandertal genome</a>. <em>Science</em>. 2010 May 7;328(5979):710-22.
