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.
