This is just one question from an archive of the National DNA Day Moderated Chat held in April 2006. The NHGRI Director and many genomics experts from across NHGRI took questions from students, teachers and the general public on topics ranging from basic genomic research, to the genetic basis of disease, to ethical questions about genetic privacy.

What does DNA tell us about the fact that animals have hair all over their bodies and humans do not?

Heidi Parker, Ph.D.: Hair growth patterning is controlled genetically much like hair or eye color. Humans do have hair all over their bodies, too, it is just lighter on the body than on the head. If you look at different people you will see that some have mnore hair than others. There are also animals that have very little hair like the naked mole rat and some breeds of dog. |
