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.
What else can I help you with?
A woman is a carrier for hemophilia what is the chances for sons with hemophilia if the father does not have hemophilia?
There are no hard answers to this, it depends strictly on luck. The statistics are though not very good for their children. Statisically the couple have a chance of having a normal son, a daughter that is a carrier for hemophilia, a daughter with hemophilia and a son with hemophia.
What chromosomes does hemophilia occur on?
Hemophilia is a X linked recessive disorder. Usually the mother is an unaffected carrier and her son unfortunately receives the X chromosome in which hemophilia is linked to.
The brother of a women's father has hemophilia her father was unaffected but she worries that she may have an affected son should she worry explain?
The woman's father being unaffected means that he does not carry the gene for hemophilia on his X chromosome. Therefore, the woman does not have the gene and cannot pass it on to her son. Her son will not inherit hemophilia from his uncle.
Is hemophilia a inherited disorder?
Yes hemophilia is a inheerited bleeding dissorder. i read it from my medical book. hemophilia means blood love and can be passed down from mother to daughter. or in some cases mother to son. it is more common for it to passed to daughters. I hope this helped. :)
Why can only the female pass hemophilia down to a son?
Males have one X chromosome and one Y chromosome while females have 2 X chromosomes. Thus wen a son is born, he inherits his father's Y chromosome and one of his mother's X chromosomes. Since the trait for hemophilia is located on the X chromosome, it must either be passed down from the mother or result from a spontaneous mutation.
How is hemophilia transmitted from the parent to the offfspring?
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.

Example Two: Mother(Non-Affected)+Father(Hemophiliac)=All sons will be non-affected and all daughters will be carriers.
In a family with parents who do not have hemophilia one son has hemophilia. Who was the carrier of the gene for hemophilia?
First of all, Spontaneous mutations account for 1/3 of the cases of genetic hemophilia. This means that 1 out of 3 people born with hemophilia have no family history of the trait prior to that person. In the scenario you are describing, you are assuming that there was a carrier when in fact, there is a good chance that there was not. There is also a chance that the child born with hemophilia received the mutation from his mother. Frequently women will have the mutation on one X chromosome but not their second. Depending od the individual case, the mother could carry the gene but not be symptomatic. It is impossible for the son to have received the gene from his father. Since in order for a boy to actually be a boy, he must receive his father's Y chromosome and not his X chromosome, a son cannot receive the affected X chromosome from his father. Also, in order for a father to pass the trait on through daughters, the father himself would be a hemophiliac.
A woman is a carrier for hemophilia what are the chances for sons with hemophilia if the father does not have hemophilia?
Since the gene for Hemophilia is carried on the X chromosome and males pass only their Y chromosome onto their sons, no their sons should not have hemophilia. Of course all daughters of a male with hemophilia will be carriers of the mutation since they with receive his X chromosome, not the Y.
What is the probability that their son has 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.
An uneffected woman whose father has hemophilia marries a man with hemophilia will the son have it to?
Almost certainly no. Hemophilia cannot be passed from father to son. There is a very slight chance (almost incalculable) that a spontaneous mutation can take place and thus make the son turn out to be a hemophiliac himself. Using the the best guess from the CDC, nearly 1/3 of hemophiliacs are the result of a random mutation. the statistic of 1 in 5000 male births is also a CDC statistic, this would imply that the son would have approximately a 1 in 15,000 chance of having hemophilia and his father's genetics would have nothing to do with it. Men and women each have 23 pairs of chromosomes. Women have two X chromosomes; men have one X and one Y chromosome. Hemophilia is an X-linked genetic disorder, which means that it's passed from mother to son on the X chromosome. If the mother carries the gene for hemophilia on one of her X chromosomes, each of her sons will have a 50% chance of having hemophilia. Hemophilia affects mostly boys, although it's very rare: Only about 1 in every 5,000 boys is born with it. The disease can affect people of any race or nationality.
How many children would have hemophilia if the female was a carrier of hemophilia and male was normal?
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.
Is hemophilia due to heredity?
Yes hemophilia is a inheerited bleeding dissorder. i read it from my medical book. hemophilia means blood love and can be passed down from mother to daughter. or in some cases mother to son. it is more common for it to passed to daughters. I hope this helped. :)
