DNA Slider is program for performing four significance tests of heterogeneity in the ratio of polymorphic sites to fixed differences in DNA sequence data. It is available for classic Macintosh, Mac OS X, and Windows. DNA sequence data analysis made easy.

The goal of the program is to identify genes that have more heterogeneity in the polymorphism-to-divergence ratio than expected under a neutral model. Peaks of high polymorphism may result from balancing selection, while areas of low polymorphism may be the result of selective sweeps.
