Answer:

In the ABO series, the gene for blood type O is recessive, while A and B are dominant genes, and AB is co-dominant.

Explanation:

According to the ABO blood system, the A blood group might have the genotype AA or AO. The B blood group might have genotype BB or BO. The O blood group will have the genotype OO. The Ab blood group will have genotype AB, A, B or O.

The O is the recessive allele but a person with O blood type can transfer blood to all other blood types. The AB is co-dominant and it can accept blood from all other blood types.

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. Maternal DNA is inherited uninterrupted from generation to generation

Explanation:

The living consort of Queen of Elizabeth ,Prince Philip, is a grand nephew of Tsar Nicholas 11. 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.

The 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, 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.
