In 1918, the Russian Tsar Nicholas II was deposed, and he and his family were reportedly executed and buried in a shallow grave.
Arte-miy333 [17]

Answer:

This can be evaluated with DNA test- by comparing the mitochondrial DNA (mtDNA)of the Tsar family with the woman-Anastasia. <u>Maternal DNA is inherited uninterrupted from generation to generation </u>

Explanation:

The living consort of Queen of Elizabeth ,Prince Philip, <u>is a grand nephew of Tsar Nicholas 11.</u> They  shared the same maternal ancestry.

Therefore, his   mitochondrial   must be maternal, and compatible with that of the Tsar Nicholar. Male children always inherit maternal mitochondria (mtDNA)and  passed from generations to generation.

T<u>he blood samples of prince Philip can be  taken, to extract the mtDNA,and matched  with the sample  of mtDNA obtained from the exhumed bodies of the Tsars,</u><u> </u>to reaffirmed the compatibility of the ancestry .  

If sample of the compatible mtDNA,  from price Phillip was compared with the mtDNA of the woman who claimed to be Anastasia, her claim can be validated.

Matched sample  shows she was the daughter, while negative result proves otherwise.
