Could two phenotypically normal parents have a child with Hemophilia A?
XhXh - with hemophilia XhXH- carrier of hemophilia
Can a girl have hemophilia?
Yes females can have hemophilia. Although very rare it has been recorded. A female can get hemophilia if her mother is a carrier and her father has it. Like I said, It doesn't happen often but is possible.
Is hemophila dominant or recessive?
hemophilia is a recessive gene, if you are A female that is a carrier then if you were to have a male child it will be passed on to him. As well as if you were to have a male child who would have hemophilia. your daughter would need to be tested to see if she carried it as well. Only Males have hemophilia but females carry it.My family has dealt with hemophilia for years.My great Aunt carrier, her son has hemophiliaMy mother a carrier, my brother has hemophilia, I do not carry it.My Aunt is a carrier, my cousin he has it, his sister carrier as well.The scientific answer isThis is due to the fact that females have two X chromosomes while males have only one, lacking a 'back up' copy for the defective gene the defective gene becomes manifest more easily in males. Because females have two X chromosomes and because haemophilia is rare, the chance of a female having two defective copies of the gene is very low, thus females are almost exclusively asymptomatic carriers of the disorder.
What gender are most people with hemophilia?
You would get it from your mother. It is a sex-liked genetic disorder. Females are the carriers, males exhibit the condition.
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.

Who can inherit hemophilia?
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.
Is it possible for a female to be a carrier of hemophilia?
Hemophilia normally refers to a genetic disorder that can be either inherited or the result of a spontaneous mutation. Since the genetic form of hemophilia is linked to a mutation on the X chromosome, males typically show the full symptoms while females with the mutation typically have somewhat mitigated symptoms or none at all. While the majority of the cases of genetic hemophilia are inherited, meaning that the genes were passed down from the the parents, approximately 1/3 of the cases are spontaneous mutations. The mutation occurs at conception, meaning that all genetic forms basically take effect at birth. Acquired hemophilia is a result of some other influence such as liver damage or specific medications. This form of hemophilia is neither inherited nor genetic. In short, technically anyone can get hemophilia. Genetic hemophilia is present at birth, and it tends to impact the health of males more than females, but can affect females too.
What is true of a woman with the genotype?
She is a carrier of hemophilia but does not have the condition
How many alleles for hemophilia do females have?
females have 2 alleles for hemophilia, (X^hX^H) and (X^hX^h) if H is the normal allele and h is the recessive allele for hemophilia
What are the chances of a person with hemophilia to pass the disease to their offspring?
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.
