In this lab, we used computer simulations to investigate about the forces of evolution. Evolution is when alleles changes over time in a population. There are four major forces of evolution. These forces may increase or decrease gene diversity, meaning they can introduce new alleles or extinct some alleles. One of the forces is mutation. Mutation is when an error, replication or deletions that cause new genes to arise that neither parents has. This causes the population to become more diversity and is unpredictable. Another force of evolution is genetic drift. Genetic drift is caused when alleles are lost by random chance. It decrease gene diversity in the population. The third force of evolution is genetic flow. Genetic flow is when alleles
