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.
Yes. People with hemophilia can have kids. Hemophilia in no way impacts the reproductive organs or process.
If the person having children is a male with hemophilia, all of his daughters will have the trait on one of her X chromosomes. A male with hemophilia will not pass the trait on to his sons as he passes only a Y chromosome on to them and not his X.
Depending on the actual genetics of the female with hemophilia (if she has a mutation on either a single X chromosome or both X chromosomes) she will either transfer the trait to either half of her children regardless of sex (in the case of a single X) or to all of her children (if both Xs have a mutation). More importantly a female with lower clotting factor levels due to hemophilia should be monitored closely as the trauma involved in the birthing process can be severe and as with any trauma to a hemophiliac, it can be more serious and prompt medical action.

There is no chance that the child will have hemophilia even if the spouse has hemophilia. Any girls the couple has will be carriers if the spouse has hemophilia.

Approximately 1 in 5000 males born have hemophilia. Approximately 1 in 10,000 children 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.
You can get it from your mom if she has the trait but that only apply to men, if your a girl you have to inherited it from your mother and father.
It is very much recessive with only one exception, which is that there is a large portion of women who simply carry the trait but dont actually have it. If you are to procreate with a female carrier than your chances of having a hemophiliac child are still not very high. You can find all the info you need by using a Punnett Square method to figure out the chances of hemophiliac children with 2 parents.
A stomach ulcer will not affect the chances of a woman giving birth. Chances of giving birth to a healthy baby are very good when proper care has been given throughout the pregnancy.
The are sujects to hemophilia, hemoraggies and other diseases.
She has 1/2 chance. We can figure out exactly what her parents' genotypes were. Her brother has a Hemophilia allele that he got from his mom. So their mom has at least 1 Hemophilia allele. If she had 2 then she would have Hemophilia. The father cannot have a Hemophilia allele because it would have been expressed. So her chances are 1/2 because her mother has 1 Hemophiliac and 1 normal allele.
