I am sorry, but I have not read the article yet. I am going to try to find time this weekend. Does it say what the genetic difference is between lactose intolerant people and other people. I know it says that a gene turns off the protein produced to process lactose, but does it say what is the difference in the gene? One base pair? 5? 10?
Just wondering if you knew? I will try to look for myself this weekend.
