Hemophilia is passed down from mother to son. It is extremely
rare for a woman to have hemophilia. It is necessary, though, for
a woman to be a carrier of the disorder for her son to acquire this
disorder. Females have two X chromosomes whereas males only
have one. When a boy is born, he takes one X chromosome from
his mother and one Y chromosome from his father. Therefore, he
can only get hemophilia through his mother.
Example One:
Mother(Carrier)+Father(Non-Affected)=50% chance of their son
acquiring the disorder and 50% chance of their daughter being a
carrier.
Example Two:
Mother(Non-Affected)+Father(Hemophiliac)=All sons will be
non-affected and all daughters will be carriers.
Haemophilia (also spelled hemophilia) is genetic disorder. It is more licely for a male to get it than female. About one of 5,000-10,000 male babies are born with Haemophilia A. About one of 20,000-34,000 male babies are born with Haemophilia B.
it is a trait passed down genetically
yes

There is no "cure" for haemophilia, only treatment with the appropriate clotting factors.
Haemophilia is a genetic disorder and is not contagious. In the specific case of Tsarevich Alexei it was passed to him from his mother Alexandra, and can be traced back to Queen Victoria.

No, it is a disease that you get from others who are infected. It is similar to how colds are passed on.
It is when you get something from someone after they die. It is also used for traits which are passed on genetically.
