Final answer:
Melissa Gymrek identified individuals from the 1000 Genomes Project using public genealogy databases, leveraging data from the Human Genome Project. This work underscores the significance of bioinformatics in personalizing healthcare. The correct answer of choice will be public genealogy databases.
Step-by-step explanation:
In 2012, Melissa Gymrek was able to identify individuals who had contributed DNA to the 1000 Genomes Project by cross-referencing information from public genealogy databases. The 1000 Genomes Project is an extension of the Human Genome Project, which was an international effort to sequence the 3.3 billion base pairs in human DNA and identify the approximately 20,000-25,000 human genes.
This project provided vital information not only for understanding our genetic makeup but also for recognizing how it can relate to various diseases and disorders. The ability to sequence an individual person's genome is a significant advancement in bioinformatics and the medical field, offering insights that can personalize patient care.
