The phenotypic correlation will be limited by the degree of genetic correlation and also by the heritability of each trait. The expected phenotypic correlation is the bivariate heritability' and can be calculated as the square roots of the heritabilities multiplied by the genetic correlation. See more In multivariate quantitative genetics, a genetic correlation (denoted $${\displaystyle r_{g}}$$ or $${\displaystyle r_{a}}$$) is the proportion of variance that two traits share due to genetic causes, the correlation between … See more Causes of changes in traits Genetic correlations are scientifically useful because genetic correlations can be analyzed over time within an individual longitudinally (e.g. … See more • Gene-environment correlation • Heritability of intelligence; g factor (psychometrics) • Cognitive epidemiology See more Genetic correlations are not the same as heritability, as it is about the overlap between the two sets of influences and not their absolute magnitude; two traits could be both highly … See more Genetic correlations can arise due to: 1. linkage disequilibrium (two neighboring genes tend to be inherited together, each affecting a different … See more Genetic correlations require a genetically informative sample. They can be estimated in breeding experiments on two traits of known heritability and selecting on one trait to measure the change in the other trait (allowing inferring the genetic correlation), … See more • Falconer, Douglas Scott (1960).
