Human Genome Project

Definition

The Human Genome Project (HGP) was an international scientific research initiative aimed at mapping and understanding all the genes of the human species, totaling approximately 20,000-25,000 genes. This groundbreaking project has greatly advanced our knowledge of human genetics, contributing to the fields of molecular biology and genetics by providing a complete reference sequence of the human genome that serves as a foundation for future research and medical applications.
