Intro Topics to Population Genetics

Population genetics is the study of genetic variation in populations, and how the variation changes from generation to generation. The most fundamental unit of genetic change is the allele. Alleles are different versions of the same gene.

One of the key questions in population genetics is: if you know how many of each allele is in a population in one generation, how will their percentages change in the next generation? An answer of "no change" is called the Hardy-Weinberg equilibrium. This theorem is an important comparison tool for finding out which genes in a genome are doing something more interesting than "neutral."
