Final answer:
The germline genome is utilized for diagnosing genetic disorders, understanding genetic variations, and aiding in the development of drugs and personalized medicine.
Step-by-step explanation:
The purpose of using the germline genome encompasses several applications, including diagnosing genetic disorders, understanding genetic variations, and as a foundation for developing new drugs and therapies. For instance, the Human Genome Project has allowed for tests for over 1,000 genetic disorders, aiding medical professionals to tailor personalized medicine based on an individual's genetic makeup. Moreover, genetic testing, facilitated by genome sequencing, can determine the risks of congenital diseases and guide decisions related to lifestyle, medication, and family planning.
