Genetics and Inheritance

Why do children resemble their parents? How is genetic information passed from one generation to the next? How can scientists use DNA to identify individuals, treat diseases, and even modify the characteristics of living organisms? In this course, students will explore the fascinating world of genetics and discover how hereditary information shapes every living thing on Earth.

Throughout the course, students will investigate the structure and function of DNA, learn how cells divide and reproduce, explore patterns of inheritance, and examine the powerful technologies that are transforming modern biology. By studying genetics, students will gain a deeper understanding of the similarities and differences among living organisms and the scientific principles that explain inheritance.
