Written by official IB examiners

Genetic Inheritance and Behaviour

Key Concepts

Genes are segments of DNA that code for specific proteins, influencing physical and psychological traits.
Heritability is a statistical estimate of how much variation in a trait within a population can be attributed to genetic differences.
Twin Studies compare monozygotic (identical) and dizygotic (fraternal) twins to estimate genetic influence on traits.
Adoption Studies examine similarities between adopted children and their biological vs. adoptive parents to separate genetic and environmental influences.

Common Mistake

Note

Heritability is often misunderstood.
It refers to populations, not individuals, and does not imply genetic determinism.
