Genetic differences exist between individuals in a population . these differences are passed on to the offspring some offspring are more likely to survive and reproduce than others if selective forces are at work genetic diversity is critical for species survival Theory of natural selection leading to adaptive evolution The science of population genetics seeks to understand how genetic variation is generated and inherited at the level of a population . What are the forces that drive variation and changes in the genetic makeup of a population from generation to generation, and how do they work? Are populations ever in a situation where they are not evolving (not adapting )?

How can evolutionary forces be detected while actually at work on a population? changes in phenotypic frequencies are reflected in changes in allele and genotypic frequencies for individual genes changes in the abundance of phenotypes indicate that evolutionary forces are at work if no changes in these frequencies occur, the population is in equilibrium Theory of natural selection leading to adaptive evolution
