WebJan 1, 2024 · A particularly useful metric of linkage disequilibrium is r 2 which is equivalent to the Pearson correlation coefficient. r 2 is calculated as D 2 /(p 1 * p 2 * q 1 * q 2) and ranges from 0 to 1.Because it is less sensitive to extreme allele frequencies than D or D′, r 2 is commonly used to describe linkage disequilibrium in genetic epidemiologic … WebExamples of how to use “linkage disequilibrium” in a sentence from the Cambridge Dictionary Labs
