Thanks, Peterhof. I imagine that the test for hemophilia is going to be difficult with such old and damaged bone fragments. Of course, biotechnology is getting more and more sophisticated every day -- it will be interesting how this whole sad story plays out over the next few decades. Hopefully the labs have preserved some samples for future investigations so that the remains at St. P+P don't have to be touched again. If they don't identify hemophilia now, scientists may be able to in the future. Or, if they do find the hemophilia gene, they may be able at a future date to discover why Alexei had a relatively manageable case of the disease. (Still horrible, of course, but RK Massie mentioned how many more bleeding episodes his son had, and how much more severe they were.) For me, it is odd to think that Alexei's remains are right here in the US pretty close to where I live...
