Genetics is the branch of biology that studies how traits are passed on from one generation to the next and why there are similarities and differences between related individuals. Prior to the discovery of genes, scientists knew that parents passed something down to their offspring, but they did not know how or what. Gregor Mendel’s famous experiments with peas indicated that certain features, such as pea texture and flower color, are encoded by two sets of traits and that the parental traits can be separated. Decades later, scientists discovered that parents passed down DNA, which was present in chromosomes. Since the discovery of DNA, we have come to appreciate the importance of chromosomes. Genomics is a relatively new field with the bold aim of understanding the function of every single gene in a genome, including the human genome. This field took off with the completion of the first sequenced genome, and after the completion of the Human Genome Project, it has attracted increasing research. Mendelian…

Learn to differentiate between DNA and RNA and between mitosis and meiosis through Education Portal's chapter on basic genetics. Our team of professional educators, who have experience in biology, designed the video lessons in this chapter to be brief and easy to follow. You'll get an overview of genetics before exploring more complex topics, like DNA mutation and comparative genomics. Other topics covered in this chapter include cloning and genetic modification. To be sure you've mastered the material covered in each video lesson, you can take the accompanying self-assessment quiz. Biology 102: Basic Genetics can help you prepare for the Excelsior College Basic Genetics exam ; passing this exam can earn you actual college credit.

The Patients and Populations sequence focuses on genetics, principles of disease, epidemiology, information gathering and assessment. The sequence features two modules: Medical Genetics and Medical Decision-Making. The growing awareness of the central role of genetic factors in the causation of human disease has made genetics one of the most rapidly developing fields in medicine. Much of this progress has been propelled by advances in the area of molecular genetics and genomics, advances that, in turn, have been applied directly to the diagnosis and management of disease. The objective of this course is to present the basic principles of medical genetics and their application to clinical medicine, with the intent of providing students the necessary background to understand ongoing developments in genetics and their application to clinical problems. The elucidation of the human genome, and the genomes of multiple other organisms, will change the way medicine is practiced. In order for physicians to understand these developments and utilize them for the benefits of their patients, they will have to be conversant with molecular genetic technologies and the technologies for acquiring, organizing, and interpreting new information.
