Linkage disequilibrium


Linkage disequilibrium Where alleles occur together more often than can be accounted for by chance. Indicates that the two alleles are physically close on the DNA strand.

Linkage disequilibrium is a measure of association between alleles of two different genes.

Linkage disequilibrium
When the observed frequencies of haplotypes in a population does not agree with haplotype frequencies predicted by multiplying together the frequency of individual genetic markers in each haplotype.

Whether a selective sweep has occurred or not can be investigated by measuring linkage disequilibrium, i.e., whether a given haplotype is overrepresented in the population.

Because of this tendency of a particular set of SNPs to remain together, called linkage disequilibrium, one can use one probe for a single SNP (called a "tag SNP") to search for the presence of the complete haplotype.
The procedure: ...

Linkage disequilibrium describes a situation in which some combinations of genes or genetic markers occur more or less frequently in a population than would be expected from their distances apart.
Full article >>>

A set of closely linked genetic markers present on one chromosome which tend to be inherited together (not easily separable by recombination). Some haplotypes may be in linkage disequilibrium.
