This introductory seminar course and the materials presented here focus on the science underlying personal genome analysis, comparison of tests available from the varied companies that dominate the direct-to-consumer genetic marketplace (e.g., Ancestry DNAFamily Tree DNAThe Genographic Project, and 23andMe), and building the knowledge to navigate the results obtained from the analysis of your own DNA sample. Materials are organized to support this course, aimed at introducing someone with only a basic understanding of biology to The Personal Genome and the discoveries that lie within, but are available to anyone. The site is actively "under construction".

COURSE OBJECTIVES:  In this course you will:

  • Contrast different types of genetic information indicative of ancestral relationships
  • Recognize the existence of genetic structure among human populations across the globe
  • Build proficiency in the conceptual foundation for the methods that underlie tests of human ancestry
  • Navigate the 23andMe web platform to view the various interpretations of genome data
  • Investigate the relationship between genotype and phenotypic characteristics with known genetic basis
  • Evaluate the personal and the potential societal impacts from commercialization of genetic tests
  • Develop skills for contributing to a productive group discussion about science and humanity
