text: As they are affected by heritabilities of both traits, genetic correlations have low statistical power, especially in the presence of measurement errors biasing heritability downwards, because "estimates of genetic correlations are usually subject to rather large sampling errors and therefore seldom very precise": the standard error of an estimate r g {\displaystyle r_{g}} is σ ( r g ) = 1 − r g 2 2 ⋅ σ
