This pathway provides an introduction to heredity and how the biological process of meiosis leads to genetic diversity. The foundational concepts of Mendelian genetics are also reviewed. For a deeper look at this topic, we recommend the pathways Meiosis and Sexual Reproduction, Mendel's Experiments and Heredity and Modern Understandings of Inheritance from the OpenStax textbook Biology for AP® Courses.
