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.

A first of its kind study found genetic associations between not just how much more attractive some of us are to mosquitoes, but the severity of the reaction to their bites.
