Doing this over and over, and associating it with information from pedigrees, we can use our sequencing information to connect specific traits with a given sequence of DNA.

Loci are said to be in linkage disequilibrium when the frequency of association of their different alleles is higher or lower than what would be expected if the loci were independent and associated randomly.

Linkage analysis quantifies the cosegregation of a disease locus and a marker locus among family members. Typically, the strength of genetic associations is expressed as an LOD score (the log-odds quantifying the probability of receiving alleles at two loci).
