(7 cards)
1
Q
what are the 6 AO1 points you must know for the influence of genes?

- Behaviour is partly inherited
-Genotype and phenotype
-Twin studies
-Concordance rates - Heritability
-Gene-environment interaction
2
Q
What does the biological approach say about genes and behaviour?
A
Behaviour is partly inherited — genes passed from parents influence traits and actions.
3
Q
What are genotype and phenotype?
A
Genotype = genetic makeup.
Phenotype = how genes are expressed through behaviour and environment.
4
Q
Why are twin studies important in genetics?
A
They compare MZ twins (100% genes) and DZ twins (50%) to measure genetic influence.
5
Q
What are concordance rates?
A
They show how often both twins share a trait. Higher in MZ twins = stronger genetic link.
6
Q
What does heritability mean?
A
It’s the extent to which traits (e.g. intelligence, schizophrenia) are due to genetics.
7
Q
Do genes act alone?
A
Do genes act alone?
