- Biological Approach
- Evolution
- Each organism has a set of genes, organism inherits these from parent
- Variations are caused by variations in genotype
- Genotype affect a physical characteristic of organism, this is called phenotype
- Evolution and Natural Selection
- 1. Organism with adaptations suitable for environment survive.
- 2. They reproduce and pass on their genes.
- 3. The offspring have this characteristic and it becomes more common in the population
- This characteristic comes about from a genetic mutation
- Genotype & Phentotype
- Genotype = Genetic makeup of individual, particular set of genes individual possesses. e.g. blood type
- Phenotype = Observational characteristic shown by an individual that are a result of both genes and environment e.g. height.
- Heredity
- Passing a trait and behaviour from parents to offspring - being able to inherit something.
