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.

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 is the Inheritance pattern of hemophilia?
If the father has hemophilia and the mother is a carrier, sons will have a 50% chance of having hemophilia. Daughters will have a 50% chance of having hemophilia and a 50% chance of being a carrier. It is very rare for both parents to have these defective genes.If the father does not have hemophilia and the mother is a carrier, sons will have a 50% chance of having hemophilia. Daughters will have a 50% chance of being carriers.If the father has hemophilia and the mother has normal blood, all sons will be normal and all daughters will be carriers.
Could two phenotypically normal parents have a child with Hemophilia A?
XhXh - with hemophilia XhXH- carrier of hemophilia
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 a sex linked recessive disorder Mary does not have the disease but both of her brothers do Neither of her parents have the disease What are Marys parents genotypes indicates pr?
Mary's father is normal and has a normal genotype XY while her mother is the carrier of hemophilia and has one X of her genotype infected i.e. she is X*X.
What are a woman chance of being a carrier for hemophilia if she phenotypically a normal woman and has phenotypically normal parents but has a hemophiliac brother?
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.
How does hemophilia progress?
Hemophilia is a recessive allele condition. Men can get hemophilia alot easier than women as the allele is found on the XY Chomosome pair. With men. they do not have the extra "tail" on the Y chromosome compared to the XX with a female. If the person has the recessive allele on the X chromosome and this person is male, they will be a hemophiliac as they do not have a 'pair' allele which could be dominant to stop the condition expressing itself. On a female, if there is a recessive (hemophilia) allele on one of the X chromosomes but on the other is a Dominant (normal) allele then she will be a carrier of the faulty gene but will not suffer from the condition herself. If the female have a recessive (faulty) gene on each of the XX chromosomes, then she will be a sufferer of the disease.
A woman with hemophilia and a man without hemophilia are expecting a baby boy. What are the chances that their son will also have hemophilia?
50%
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.
A male who has normal vision marries a female who is a carrier for colorblindness can they have a colorblind daughter?
Assuming that the man who has normal vision is homozygous for normal vision, the couple's daughter will either be homozygous for normal vision or heterozygous (normal vision but carrier for color blindness) for normal vision. In light of this, the couple's daughter will not be color blind.
What is a punnett square for sickle cell anemia?
Since you did not specify what parental cross you wished to represent this is the best I can do for you. A "normal" male would be represented as XHYo - gametes XH and Yo A male with hemophilia would be represented as XhYo - gametes Xh and Yo A female non-carrier would be represented as XHXH - gametes XH A female carrier would be represented as XHXh - gametes XH and Xh A female with hemophila would be represented as XhXh - gametes Xh
