3.29 Species Variation

Variation within a species can be
- Genetic
- Environmental
- Both

Variation -> differences in phenotype (determined by Variation = Genotype + Environment)
[Continuous variation]

1. Variation entirely dependent on genotype.
e.g. blood group (A, AB, B, O...)

2. Variation modified by the environment

e.g. tallness (inherited with genotype but diet may influence it)








3. Environmental variation
Entirely dependent on environment
Cannot be inherited genetically

e.g. home language
