Wright-Fisher Model

The Wright-Fisher model is a mathematical way to understand how gene frequencies change over generations in a population. It assumes a fixed population size and that each new generation is formed by randomly selecting genes from the current one, with some chance of genetic variation occurring. This randomness can lead to certain genes becoming more common or disappearing entirely over time. The model helps scientists study genetic drift, the role of chance in evolution, and how populations evolve over generations. It is a foundational tool for understanding genetic variation in populations.
