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
visibility controls.
Corresponding to each of these tracks are separate
tracks for carriers and non-carriers of the PRDM9 14/15 composite
allele which 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, respectively,
for 15,257 parent-offspring pairs. For more information on this map, see
Kong, 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.

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.
