What is heritability?

Heritability is the proportion of the variance in a trait that is due to genetic factors.

How does the heritability of intelligence change from childhood to adulthood?

The heritability of intelligence increases dramatically from childhood to adulthood.

Explain the concept of genotype-environment correlation in relation to intelligence.

Genotype-environment correlation refers to individuals selecting, modifying, and creating environments that are correlated with their genetic predispositions.

What is genetic amplification and how does it relate to intelligence?

Genetic amplification suggests that small genetic differences may become magnified as individuals develop. Signup and view all the answers

What is Genome-wide Complex Trait Analysis (GCTA) and how does it estimate genetic influence?

GCTA is a method that estimates the net effect of genetic influence using DNA of unrelated individuals by predicting phenotypic similarity based on genetic similarity. Signup and view all the answers

What did a recent twin study find about the genetic correlation of intelligence between ages 7 and 12?

The genetic correlation of intelligence between ages 7 and 12 was 0.75, despite increasing heritability from 0.36 to 0.49. Signup and view all the answers
