Gregor Mendel, a Moravian Augustinian friar working in the 19th century in Brno, was the first to study genetics scientifically. Mendel studied "trait inheritance", patterns in the way traits are handed down from parents ...

What Is Genetics? - National Institute of General Medical Sciences
Genetics is the study of genes and heredity—how traits are passed from parents to children through DNA. A gene is a segment of DNA that contains instructions for building one or more molecules that help the body work. Researchers estimate that humans have about 20,000 genes, which account for about 1 percent of our DNA. The remainder of the DNA plays a role in regulating genes, and ...

What is genetics? What is genomics? And what is the difference?
What are genetics and genomics? Genetics involves scientific studies of genes and their effects. Genes carry the instructions for making proteins, which direct the activities of cells and functions of the body. For example, genes determine characteristics like our hair color or texture or the shape of our ears.
