Heritability could increase if genetic variation increases, causing individuals to show more phenotypic variation, like showing different levels of intelligence. On the other hand, heritability might also increase if the environmental variation decreases, causing individuals to show less phenotypic variation, like showing more similar levels of ...

Heritability studies – studies focused to determine whether a trait, such as aggression, is heritable and how it is inherited from parent to offspring. These studies make use of genetic linkage maps to identify genes associated with certain behaviors such as aggression.
"Heritability is caused by many genes of small effect." "Phenotypic correlations between psychological traits show significant and substantial genetic mediation." "The heritability of intelligence increases throughout development." "Age-to-age stability is mainly due to genetics." "Most measures of the 'environment' show significant genetic ...

The display of the influence of heritability and environmentality differs drastically across age groups: the older the studied age is, the more noticeable the heritability factor becomes, the younger the test subjects are, the more likely it is to show signs of strong influence of the environmental factors.
