What's your question?

Questions on this site are answered by scientists (not physicians!), who cannot give medical advice. If you have a medical question, please consult with your doctor. Also, our scientists will not answer homework questions (though they appreciate the ingenuity of those who ask!).


Due to the volume of questions received, it is not possible to respond to every submission. However, every question is reviewed carefully by Abbey Thompson, Ph.D., director of the Ask A Geneticist program. Your question may be lightly edited and published on this website, along with an answer.

Please make sure you use an address that can receive emails from an external source. Many school-provided email addresses will block messages, which means you would not receive a reply.
