Which measure allows behavior geneticists to determine the percentage of similarity in phenotype among pairs of family members and is used mostly to examine mental disorders?

Question

Quizplus · Accepted Answer

The concordance rate is a measure used to determine the percentage of similarity in phenotype among pairs of family members, specifically examining the presence or absence of a certain disorder or trait. This measure is used mostly to examine mental disorders. Option A (genetic correlation) refers to the degree of similarity between two different genes or how those genes interact with each other, whereas option B (heritability estimate) refers to the proportion of variance in a trait that can be attributed to genetic factors. Option D (chromosomal correction) is not a commonly used term in behavior genetics.
