In Chapter 9, Heredity and Evolution, students explore the fascinating concepts of genetic inheritance and the process of evolution. This chapter delves into how traits are passed from parents to offspring through genes, as well as the principles of dominant and recessive traits discovered by Gregor Mendel. It also covers variations in species, natural selection, and the role of mutations in evolution. By understanding heredity and evolution, students gain insight into how diversity in life forms has developed over generations, shaping the complex web of life on Earth. This chapter encourages students to appreciate the scientific basis behind genetics and the ongoing evolution of species.
