Simplest Population Models

In this chapter we will show how even simple models, describing the most elementary populational genetic processes, bring us to conclusions, which are interesting due to their biological clearness. Simple models are still better since they are readily verified in experiments, clearly demonstrating their merits and drawbacks and showing to what extent mathematical models may be applied to the analysis of populational genetic processes. A complex model of great generality is hard to apply to concrete biological situations. The arising mathematical complications can totally shade the biological origin of the problem, shifting the basic accent of the study onto the lines of their overcoming.
