PSY302 Genes

Polygenic inheritance

most traits are influenced by several genes

Phenotypic plasticity

how much a trait can change because of the environment

Types of phenotypic plasticity

1. low (canalization) - no plasticity

2. high - the same genes can look different in the different environment (shyness, aggression)

3. norm of reaction - the range of outcomes the genotype can show across different environments 

Epigenetic 

complex process where environment can shape the genetic code expression

genetic-environment interaction

1. environmental factors can affect whether genes are turned on/off

2. env factors can alter the magnitude of genetic effects on development

3. genes expression affect how ppl respond to children

4. your genes influence the environment you choose to experience

how genotype interacts with environment to determine behavioural attributes

behavioral genetics

heritability

the share of differences between people that comes from genes
