Dr. Botkin : You stuck the Tsar!
Dr. Botkin : The female is the carrier. The mother gives it to the son. Your mother got it from her mother, Queen Victoria, and passed it on to you.
Tsarina Alexandra : I see.
Dr. Botkin : It strikes some males and misses others. Of Victoria's four sons, just one had hemophilia.
Tsarina Alexandra : And just one of mine.
