A lod score is a statistical calculation used to determine the probability that two genetic traits are linked by analyzing pedigrees. It stands for logarithm of the odds and involves comparing the likelihood of observing certain pedigree patterns if the two traits are linked versus if they are not linked. A lod score greater than 3 indicates strong evidence for linkage, while a score less than -2 indicates strong evidence against linkage.
