（单词翻译）

So how did scientists confirm that it was hemophilia that plagued the royals? By analyzing¹ the DNA² of Victoria’s great grandson, Prince Alexei Romanov. He was murdered along with his entire family during the onset³ of the Russian Revolution in 1918. Using bone fragments, the scientists identified genetic⁵ markers for hemophilia B. Prince Alexei shared the same troublesome DNA as other male members of Queen Victoria’s exclusive gene⁴ pool. So the finding confirmed that all the royals who bled to death did so because of hemophilia. Today, clotting⁶ factors and other medications can effectively control hemophilia. But during the 19th century, when no remedy was available, bleeding without end usually meant that you’d reached the end–royalty or not.
