Population Genetics Defined

The idea
Population genetics studies how selective forces change a population over generations by tracking shifts in that population's allele and genotype frequencies.
In practice
Measuring a specific allele's frequency in one generation, then measuring it again several generations later, is a basic population-genetics study.
Where people slip
Population genetics tracks a population's allele and genotype frequencies over time — it does not track any one individual's genotype changing.
