The measure that allows behavior geneticists to determine the percentage of similarity in phenotype among pairs of family members and is used mostly to examine mental disorders is the concordance rate. Concordance rate measures the proportion of pairs of individuals in which both have the same disorder or trait. It is mostly used to examine the heritability of mental disorders because such traits are complex and influenced by both genetic and environmental factors. Genetic correlation measures the degree to which two traits or disorders are influenced by the same set of genes. Heritability estimate is a measure of the proportion of variation in a trait or disorder that can be attributed to genetic factors. Chromosomal refers to the arrangement of genes on a chromosome.
