Genetics in Action: Genetic Disorders

The video discusses mutations in plants, animals, and humans, explaining that most mutations are harmless but can sometimes lead to genetic disorders. Sickle cell anemia is highlighted as a genetic disorder affecting red blood cells, primarily in individuals of African descent. The video also explores how environmental factors like chemicals and UV radiation can influence genetic disorders, such as skin cancer.

• Semicircle

• Square

• Triangle
