Genetic Concepts and Terminology

The video provides an overview of basic genetic concepts, explaining the structure and function of cells, chromosomes, and DNA. It discusses how chromosomes are organized in pairs, including sex chromosomes, and how genes instruct the body to produce proteins. The video also covers genetic variants, such as copy number and sequence variants, and their potential impact on health. Contact information is provided for further inquiries.
