genotype-phenotype

genotype-phenotype

1. genes influence structure and function of body

   • genotype is collection of all individuals genes - identical within each cell - does not change

2. genes interact with fluid environment in cell - cell interacts with neighbours - whole organism interacts with environment

   • interaction in development is called phenotype - physical structure and behaviour of organism

3. features of phenotype change from experience - environment (muscle / aggression etc)

   • phenotype can vary between genetically identical individuals - raised in different environments

4. genotype has potential for development into number of phenotypes

   • important genotype/phenotype distinction - gentic basis for differences in a population - interaction with environment needs to be considered when looking at development and behaviour
