## Description

This track shows the SNPs that were used in the calculation of Tajima's D (Tajima, 1989), a measure of nucleotide diversity, estimated from the Perlegen data set (Hinds et al., 2005). Tajima's D is a statistic used to compare an observed nucleotide diversity against the expected diversity under the assumption that all polymorphisms are selectively neutral and constant population size.

## Methods

See the Tajima's D track or Carlson et al. for more details on the use of this track.

## Credits

This track was created at the University of Washington using gfetch from the Nickerson Laboratory and the R statistical software package.
