Background: Anna Anderson claimed for more than 60 years that she was Princess Anastasia. In addition, Anna Anderson knew a great deal about life in the Russian palace and she could speak very knowledgeably about the family members. Anna had many people convinced that she was Anastasia. Does the DNA support her claim?
In this activity, you will examine the STR profiles and Anna Anderson, along with those of Tsar Nicholas and Tsarina Alexandria. In this way, you will determine if the DNA evidence supports the claim that Anna Anderson was the child of the tsar and tsarina. Recall that each parent must contribute one STR allele at each STR locus.
Below is the data table of the STR results for Tsar Nicholas, Tsarina Alexandria, and Ana Anderson. Note that there are five STR loci: VWA, TH01, F13A1, FES/FPS, and a test for amelogenin (AMEL) which indicates sex
