- biological structures and neurochemistry on behaviour
- genotype and phenotype
- genetic basis of behaviour
- evolution and behaviour

- 23 pairs of chromosomes (inherited)
- there are genotypes that form basis of our development
- genetic makeup = basis for behaviouR
- genes: carry instructions for characteristics
