sunny was there any clue why that scheleton was in such bad conditions?
In the video i was talking about they showed the remains of alexei and another human - they were not skeletons, nor skulls, just fragments of bones, that after analyse, showed to be human. They didnì't resemble to a skeleton at all! Just pieces of bones - it was like seeing Csi Las Vegas!
Not joking now, this is what i saw in the video - it's so interesting, you really should see it on Youtube. I saw both in english and in italian, just to be sure i had well understood. Because of the bones were so few, it wass very hard extract DNA. as i said.
I remember they said the bones were so few and in so bad conditions 'cause the Bolsheviks had tried to burn these two corpses. In fact, there were ashes in that graves, and those pieces of skeletons were partly burned, too. In fact Yurovskij wrote they tried to burn two corpses - Alexei and his mother, but they took Demidova instead of Alix. In fact, it turned out they took neither Alix nor Demidova, but one of the girls - Maria or Anastasia, we still don't know for certain. (you find all this stuff about Yurovskij in
The Fate of The Romanovs)
So, it's impossibile to say how tall the girl with alexei was. what the forensics have found is that there are two different human beings - a young male and a young female. the male turned out to be genetically son of the skeletons identified as Nicholas and Alix; the female had 13 genes in common with the male, so they were without doubt brother and sister.
Alas, genetics can't say wether the girl was Maria or Anastasia.
