AP Biology Test On Mitosis And Meiosis! Trivia Quiz - Quiz

Cell division occurs in two major ways, and the difference between the two is the results of the processes. While cells resulting from mitosis are diploid, those resulting from meiosis are haploid. In this AP biology test on mitosis and meiosis, you will get to review what you understand about the two processes and how they occur within living things.
