The text suggests that, from a genetic point of view, the concept of race is:
◦ very important, since there are many genes in the human genome that determine specific race-related traits (such as hair color and eyelid shape)
◦ largely meaningless, and a better way of thinking about race differences is to consider them as cultural or ethnic differences
◦ very important, since in humans there are only a handful of genes that code for "race" in our DNA (each corresponding to a difference racial group)
◦ of some importance, since genes that code for racial characteristics also code for intelligence
