Where’s the heritability? Right where you’d expect—if you look close enough

Biologists have at our disposal two major ways to assess how much genetics contributes to variation in the most interesting traits, or phenotypes, of our favorite study organisms—that is, the heritability of those phenotypes. There’s what you might call the … Continue reading
