Witryna13 wrz 2024 · The 95% confidence interval for IQ heritability is 21% to 64%, so the chances are 95% that the true value of heritability lies within that range. Ergo, IQ is pretty damn heritable. In contrast, the proportion of variation due to parental environment (adoptive parents) is estimated atjust 1%, with a 95% confidence interval of 0% to 2%. … Witryna28 cze 2012 · So if heritability is 1.0 all of the variation is due genetic variation; offspring are just a linear combination of their parents. If heritability is ~0.0, then there's basically no correlation between parents and offspring. Though, as I said, heritability is a population-wide statistic, it can be informative on an individual level.

When the genetic effect on a trait is strong, the trait is highly heritable. The reverse is also true. When the genetic effect on a trait is weak, it is lowly heritable and the environment has the greatest influence on that trait.
