WebbLinkage disequilibrium (LD) is the nonrandom association of alleles at two or more loci. The standard measures of LD strength are described in detail, including extensions to multiple alleles. When there are different numbers of alleles at two loci, there are asymmetries that are not captured by standard measures.
