Genetics is the study of heredity and the variation of inherited characteristics. It explores how traits are passed from parents to offspring through genes, which are segments of DNA. Understanding genetics helps us comprehend the biological basis of traits and diseases, and it plays a crucial role in fields like medicine and agriculture. The field of genetics has advanced significantly with technologies such as CRISPR, which allows for precise editing of genes. This has opened up new possibilities for treating genetic disorders and improving crop resilience. As we learn more about our genetic makeup, we can better understand our health and evolution.
