The document discusses several methods that scientists are exploring to address the shortage of organs available for transplant, including cloning pig organs and 3D bioprinting of organs. It also provides background on the Human Genome Project and genetic disorders. While cloning pig organs could help reduce transplant waitlists, it may not eliminate organ rejection issues. 3D bioprinting aims to print organs using a person's own cells to prevent rejection, but the technology has not yet been perfected. The Human Genome Project mapped the human genome to further medical research and treatment of genetic diseases.
