Наследуемость IQ высока, где-то в районе 0,7 - 0,8 для взрослых (у детей наследуемость IQ меньше - это обычная картина для количественных мультигенных признаков: пока организм растет, на него сильно может влиять среда, обучение, а с возрастом, увы, всё подравнивается под гены). Напомню, что наследуемость - это, говоря упрощенно, доля изменчивости по признаку, определяемая генами, а не средой. Речь идет только об изменчивости (будь у всех людей одинаковый IQ, сама постановка вопроса о наследуемости этого признака была бы бессмысленной).

http://en.wikipedia.org/wiki/Heritability
Heritability asks how much genetics are playing a role in differences in height between people. This is not the same as asking how much genetics influences height in any one person.
Conflation of heritability with genetic determination Arguments for biological determinism typically conflate the term "heritability" with genetic determination of a trait. Heritability is simply a measure of phenotypic variance within a population that is able to be explained in terms of genetic as opposed to environmental factors. This means that a heritability estimate will change when the environment is changed. Heritability estimates also apply only to a specific population in relation to its environmental context. So, for instance, if a trait is said to be 60% heritable, it means that 60% of the variance of the trait for the population measured can be explained by genetic factors in the context of the environment in which the measurement was taken. It does not mean that the trait is 60% genetically determined in all times and all places.
