…project made possible by DNA technology is the effort to map the entire human genome. Four complementary approaches are being used: 1. Genetic (linkage) mapping of the human genome. 2. Physical mapping of the human genome. 3. Sequencing the human genome. 4. Analyzing the genomes of other species. These four approaches are yielding data that together will give a complete map of the human genome and an understanding of how the human genome compares to those of other organisms
