Completing the Text on Genetics

1. Which choice most logically completes the text? The study of genetics has unlocked numerous secrets of heredity and evolution. Genetics is the branch of biology that delves into the inheritance of traits and the role of genes in shaping living organisms. By understanding the genetic code and the mechanisms of inheritance, scientists have made remarkable strides in medicine. For example, breakthroughs in medical genetics have led to the development of innovative treatments, such as gene therapies for inherited diseases like cystic fibrosis. These treatments address the root causes of genetic disorders by modifying or replacing faulty genes, marking a significant advancement in medical science. Ongoing genetics research is continually revealing connections between genes and various diseases, suggesting ________. O potential approaches for genetic engineering and cloning O promising avenues for the prevention and treatment of illnesses O a diminishing role of genetics in modern science O limitations in our current understanding of genetics and heredity
