Leave Your Genome to Science

Here's a question: When people agree to donate their body to science, will their genome be part of the deal? And will that make people even less inclined to donate? Note: Google "leave your body to science" and three paid ads come up, including one for LifeLegacy.org, an organization that organizes and encourages whole body donation. Curiously, there's a link to "Testamonials". Uh, how is that possible?
