- INTRASPECIFIC is caused by genetic and enviromental factors
- Genetic
- Same Genes = Same species
- Different versions of those genes are called alleles
- The alleles an organism that has make up its GENOTYPE
- Different genotype = variation in phenotype (characteristcs
- You inherit from parents specific factors e.g eye colour
- Same Genes = Same species
- Enviromental

- Investigating Variation
- Usally you take a sample of a population not whole thing because it is impossible and time consuming
- Random Sample
- Diving field in to a grid and use random generator
- Diving field in to a grid and use random generator
- Standard Deviation
- Tells you how much of the values in a single sample vary.
- Large SD = Vary alot!
- Small SD: Vary alittle around mean value
- Tells you how much of the values in a single sample vary.
- Usally you take a sample of a population not whole thing because it is impossible and time consuming
