Final answer:

The two sons of Queen Victoria, Alfred and Arthur, did not have hemophilia because they did not receive the recessive gene from their mother.


Step-by-step explanation:

The two sons of Queen Victoria, Alfred and Arthur, did not display hemophilia because they did not receive the recessive gene (XD) from their mother. Hemophilia is an X-linked recessive disorder, which means that the gene responsible for hemophilia is located on the X chromosome. In order for a male to have hemophilia, he must inherit the recessive gene from both his mother and father. If a male inherits a dominant gene or a normal gene from his mother, he will not have hemophilia.
