Anomalous PCR product

[The Great American Gene Company]

Dear Folks:

I was just contacted by a colleague with the following question.  It is
not my field of expertise, but I believe that it is similar to a topic
recently discussed here.  Can we have your comments and/or
observations?  Both Neal and I would greatly appreciate any help you
can provide.
