Being heterozygous requires having two different genes for the same thing. Examples would be getting the gene for blue eyes from your father and brown eyes from your mother. This would make a person heterozygous for blue & brown eyes.
Since the mutation for hemophilia is only carried on the X chromosome, males can not have two genes for it seeing as how males have one X and one Y.

Will a heterozygous female with hemophilia have blood that will clot normally?
Yes, because Hemophilia is recessive (if you have a normal allele, you won't have hemophilia, and heterozygous means that you have one normal and one abnormal allele).
What are the offspring of hemophilia?
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.
Are some boys carriers for hemophilia?
A male with hemophilia does in fact carry the genes and can pass them on to his daughters, so yes, some boys (if they have hemophilia) are carriers.
What are the statistics of hemophilia?
1 in 5,000 male birth
Is hemophilia communicable?
Hemophilia is not contagious by any means, however it can be passed from parent to offspring in the way of genetics.
What gene does hemophilia affect?
The gene that causes hemophilia is located on the X chromosome. A woman who gives birth to a child with hemophilia often has other male relatives who have hemophilia. Sometimes, a baby will be born with hemophilia when there is no known family history. This means the gene can be"hidden"( or passed down through several generations of female carriers without affecting any male members of the family) or the change in the X chromosome is new (a spontaneous mutation).
How can a lady have hemophilia will it effect menstrual period?
Normally a woman is only a carrier of hemophilia, but if her mother is a carrier and her father has hemophilia the female does have a chance to get it. It is very rare for this to happen but It has been recorded.
If you have hemophilia and scrape your knee why does it keep bleeding?
When you have hemophilia, the proteins that clot your blood are not being created and therefore, a scab cannot be created to effeciently stop the bleeding.
What are some famous cases for hemophilia?
Abraham Lincoln had hemophilia, along with Mother Theresa and Ghengis Khan, the Owners of Walmart in DesAllemands, and Alexi Romanov, Anastasia's brother
What genotype is not true-breeding?
An individual with a heterozygous genotype cannot be true-bred.
What do you get when you cross a male hemophiliac with a female hemophiliac?
The gene for hemophilia A is found on the X chromosome (it is a sex-linked recessive disorder). Women have two X chromosomes and men have one X chromosome. A woman with hemophilia (very rare) would have the mutated gene on both of her X chromosomes. This means that all of their children, both male and female would have hemophilia.
Do Male hemophiliacs inherit the disease from their?
Male hemophiliacs inherit it from their mother, because hemophilia is only on the X gene and males only have one and it is from their mother.
