2008 National DNA Day Online Chatroom Transcript

This is just one question from an archive of the National DNA Day Moderated Chat held in April 2008. 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.

Is there reason to believe the Y chromosome could "disappear"?
     Phyllis Frosst, Ph.D.: Investigating genetic discrimination, direct to consumer marketing of genetic tests and pharmacogenomics. It's possible that the Y chromosome could disappear, but the pace of evolution is very slow and the Y chromosome has a lot of important genes on it. Scientists estimate that it would take on the order of 10 million years for a big genomic change like that to occur.
