Document Summary
Population genetics analyzes the amount and distribution of genetic variation within and between populations, and seeks to infer the forces that control the variation. This is the root of genetic variation and biodiversity, and the way of producing evolutionary differences. Classical genetics tend to focus on what the gene does and doesn"t take into account evolutionary forces. At the population level, genetic variation can be seen in various recessive traits; the job of population genetics is to interpret these variations through space and time. For example, sickle cell anemia is a recessive trait which is concentration in central. Africa more than anywhere else in the world. Albinism is another example of genetic variation which has its own characteristics. Population genetics has helped prove the african roots of the human race. The first map shows the sickle cell anemia proportions we discussed before.
