3.29 - species variation

- variation = differences in phenotype
- variations of phenotype means they have different genotypes and live in a different environment
- there are different types of variation populations
1) all due to a variation genotype i.e. blood type
2) due to genotype and environment i.e. humans
3) environmental variation (no genotype) i.e. language
