## Description

The deCODE recombination rate track represents calculated rates of recombination based on the deCODE recombination maps in 10 Kb bins from October 2010. Sex averaged-, Female- and male-specific recombination rates can be displayed by choosing the appropriate options on the track description page.

Corresponding to each of these tracks separate tracks for carriers and non-carriers of the PRDM9 14/15 composite allele can be displayed as well. There are also tracks depicting the difference between male- and female- recombination rates, and a track showing recombination hotspots, i.e. bins with standardized recombination rates higher than 10.

In addition to the deCODE display, three data tracks from the HapMap project are included. CEU, YRI and combined maps from release #24 can be turned on with the track visibility controls.

## Methods

The deCODE genetic map was created at deCODE Genetics and is based on 289,658 and 8,411 SNPs on the autosomal and X chromosomes for 15,257 parent-offspring pairs. For more information on this map, see Kong, A. et al. (2010).

Each base is assigned the recombination rate calculated by assuming a linear genetic distance across the immediately flanking genetic markers. The recombination rate assigned to each 10 Kb window is the average recombination rate of the bases contained within the window. The recombination rates are standardized, bringing the average to 1 for all bins used for the standardization.

## Credits

This track was produced at UCSC using data that are freely available for the deCODE genetic maps. Thanks to all who played a part in the creation of these maps.
