Detailed explanation-1: -Genetics is the scientific study of genes and heredity-of how certain qualities or traits are passed from parents to offspring as a result of changes in DNA sequence. A gene is a segment of DNA that contains instructions for building one or more molecules that help the body work.
Detailed explanation-2: -Genetics research studies how individual genes or groups of genes are involved in health and disease. Understanding genetic factors and genetic disorders is important in learning more about promoting health and preventing disease.
Detailed explanation-3: -(jeh-NEH-tix) The study of genes and heredity. Heredity is the passing of genetic information and traits (such as eye color and an increased chance of getting a certain disease) from parents to offspring.
Detailed explanation-4: -To answer these questions, they study a type of biology called GENetics (juh-net-icks). “Gen” means beginning. Parents pass traits on to their children. Genetics is the science of genes and how traits are passed on from one generation to the next. People who study genes are geneticists (juh-net-i-sists).
