Many empirical studies have shown highly significant levels of LD, and
often strong associations between nearby SNPs, in the human genome.
Because the likelihood of recombination between two SNPs increases
with the distance between them, on average such associations between
SNPs decline with distance.
Average linkage disequilibrium, |D|, vs.
distance between SNPs for 2597
genes in which accurate distances
were available.
Lower values indicate a stronger effect
of recombination and recurrent
mutation.
LD decreases with distance.
