Her father has to have hemophilia as well, and the mother is a carrier or also has hemophilia. So if we pretend that the hemophilia gene is "x", you need to have "xx" to have hemophilia. The father must have the genotype "Yx" and the mother has the have "Xx" or "xx".
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.
If both parents have x-linked hemophilia, the father's genotype would be XhY and the mother's genotype would be XhXh, which is astronomically rare. If this did happen, all of their children would inherit x-linked 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.
if a man were non- hemophiliac and he marries a woman whois homozygus for nan-hemophilia,give the possible genotypes of the children

Hemophilia is a condition where the blood does not want to clog up or clot in an open wound or abrasion. The cause is a factor deficiency in the plasma of the blood needed to coagulate the blood for it to clot.It is sex-linked genetic disorder where females carry the condition and pass it on to their children; males exhibit the condition. At present, there is no cure.
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.

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.
All Girls will be carriers of Hemophilia. All Boys will be unaffected (they won't have Hemophilia).
She is a carrier of hemophilia but does not have the condition

It is possible but extremely rare.
Anyone can inherit hemophilia. In most cases, it is a man whose mother is a carrier of the disease. It is extremely rare for a woman to have hemophilia but it is not uncommon for one to be a carrier. It is even possible for someone whose family has no record of hemophilia to get it through gene mutations.
You would get it from your mother. It is a sex-liked genetic disorder. Females are the carriers, males exhibit the condition.
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.
