Discontinuous variation
- Qualitative differences in the phenotypes of individuals within a population give rise to discontinuous variation
- Qualitative differences fall into discrete and distinguishable categories, usually with no intermediates (a feature can’t fall in between categories) For example, there are four possible ABO blood groups in humans; a person can only have one of them
