Queen Victoria had 1 (Leopold) out of four male offspring with hemophilia. What was the probability of this scenario?   Hemophilia is known as "The royal disease" because many of the European royal families had members afflicted with it. A really famous case was Queen Victoria's (1819-1901) descendants who spread the disease across Europe, from Spain to Russia. You can see the pedigree of Queen Victoria's family here:Hemophilia is an X-linked recessive disease. With the information provided, please answer the following questions:

Inheritance and Mendelian Genetics

Inheritance means the passing of traits to offspring from parents. These traits could be passed either through asexual reproduction or sexual reproduction. The offspring receives the genetic material from the parents. Mendelian inheritance is a certain biological inheritance that follows the rules and principles laid down by Gregor Mendel in 1865. The initial hypothesis was considered wrong, but other inheritance theories modified the concept of inheritance and thus genetics.
