What will occur to each of real frequency in the population?

In a population, real frequencies of traits or characteristics can change due to various factors such as natural selection, genetic drift, mutation, and gene flow. These processes can lead to an increase or decrease in the prevalence of certain traits over time. For example, advantageous traits may become more common, while less favorable traits may diminish. Ultimately, the real frequency of traits reflects the dynamic interplay of these evolutionary forces.
