<<Disclaimer: Verify this information before applying it to your situation.>> I have a question I haven't seen addressed on the list. I would be interested in knowing whether certain blood types (A postive, O positive, etc) show up more often than others. Also where there are celiac parents with celiac children, do the children with celiac share the same blood type more often than not. This may be a stupid question but I am curious. Thanks, Brenda
