Queen Victoria of England had a son, Leopold, and a great-grandson, Tsarevich Alexei Nikolaevich Romanov of Russia, both of whom had hemophilia. We can conclude that:
 
  a. Queen Victoria must have had hemophilia, too.
 b. Queen Victoria was a carrier for hemophilia.
 c. Queen Victoria's husband, Prince Albert, must have been a carrier.
 d. Leopold and Tsarevich Alexei probably developed hemophilia due to a spontaneous mutation, because their female relatives did not have the condition.
