A majority of Americans agree that someone’s racial identity is not hard-wired into their DNA, according to a new survey on attitudes about race and genetics by researchers at Northwestern University working in collaboration with DNA testing company 23andMe.

23andMe released a new batch of trait reports that look at whether your DNA indicates you might be tastier to mosquitoes than others, or why you can sing back a musical note or get the heebie-jeebies looking down from great heights, or even why your hair lightens in the sun.

23andMe has added new and more diverse reference populations, allowing customers with African and East Asian ancestry to see a more detailed breakdown of their Ancestry Composition. The update was made possible thanks to the contributions of 23andMe customers, as well as new sources of publicly available data such as the 1000 Genomes Project, and from the company’s own African Genetics Project.

He Richard had long ago stopped expecting he’d find anything about his biological family, but 23andMe helped the 50-year-old adoptee find his half-sister and learn about his biological family.
