In short, hemophilia has nothing to do with colorblindness, but YES, they could have a colorblind child if she is a carrier for the colorblindness gene.
Color blindness is an X-linked trait. That means it is carried in the X chromosome, which differentiates whether a baby will be a girl or a boy. Women have two X chromosomes (XX), and men have an XY combination. If a woman is a carrier for color blindness, only one of her chromosomes will be affected (we'll call it a little "x"), and for that reason she will not be colorblind. Men, on the other hand, only have one X chromosome, so any time they carry the colorblindness gene, they will be colorblind. A woman will carry the colorblindness gene if:
a. Her father is colorblind
b. Any of her offpsring are colorblind
She may carry the colorblindness gene if:
a. Male family members (brothers, uncles, etc.) are colorblind
A child inherits one chromosome from each parent. He/She will get an X chromosome from his/her mother, and an X from her father (if a girl) or a Y from his father (if a boy).
So, If a woman has normal vision (assuming she does not have a family history of colorblindness), XX, and a man is colorblind, xY, they have several different chances for different offspring:
Xx (a normal girl who carries the colorblindness gene)
XY (a normal boy)
Xx (a normal girl who carries the colorblindness gene)
XY (a normal boy)
The short answer is that ALL CHILDREN WILL HAVE NORMAL VISION. However, all daughters will be CARRIERS, meaning they can pass colorblindness on to their children.

What is a carrier for hemophilia?
A carrier for hemophilia is a female who carries the genetic mutation for hemophilia on one of her X chromosomes, but does not exhibit symptoms of the condition herself. Carriers can pass on the gene mutation to their children, resulting in hemophilia in male offspring. Testing can confirm carrier status.
How many woman have hemophilia in the US?
The actual number of women diagnosed with hemophilia is very hard to pin down. Doctors do not even agree on what designates a female as having hemophilia. Some believe that both X chromosomes would need to have the mutation, while others diagnose using the clotting factor levels. Due to the occurrence of what some doctors call incomplete dominance by the non-affected X chromosome the mutation can lower a "carrier's" clotting factor below what would qualify any male as having hemophilia.
How can a lady have hemophilia will it effect menstrual period?
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.
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.
Sam has hemophilia. Sam's brother mother and father do not have hemophilia. Draw a pedigree showing who has the disorder and who is a carrier?
In a pedigree chart, Sam would be represented by a filled square (male) or circle (female) to indicate that he has hemophilia. Since Sam's brother, mother, and father do not have hemophilia, they would be represented by unfilled squares (male) or circles (female). However, Sam's mother would be a carrier of the hemophilia gene, so she would be represented by a half-filled circle. The pedigree would show Sam with hemophilia, his mother as a carrier, and his brother, father, and other family members without the disorder.
What chromosome number is hemophilia on?
Hemophilia is a Sex-linked genetic disorder. It is found on the X chromosome of chromosome 23.A carrier for Hemophilia(represented by H(dominant) or h(recessive)) would look like this:XHXh(Female)*Males are not carriers for hemophilia-They are either affected or they're not*An affected person would look like this:XhXh(Female) XhY(Male)Someone who is neither a carrier nor affected would look like this:XHXH(Female) XHY(Male)
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.
What causes haemophilia?
Hemophilia is a disorder that is defined by the absence of one or more proteins required for blood clotting. If a person with hemophilia is injured, the bleeding is prolonged because a clot forms very slowly. This can lead to massive internal as well as external bleeding from serious injuries.
What are the offspring of 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.
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.
If parents with hemophilia have a child Will that child have hemophilia?
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.
How can a person get hemophilia?
The majority of hemophilia cases are genetic and the individual is born with it. Approximately 1/3 of the cases of genetic hemophilia are spontaneous mutations in that person while the other 2/3 of cases inherit the mutation from their parents. Since the mutation is located on the X chromosome it traditionally has a larger impact on males (having only one X, they lack the secondary set of genes to offset that mutation). Acquired hemophilia, while much more rare can be caused by various conditions. Since the clotting factor proteins are primarily produced in the liver, liver disease, liver damage, and even certain medications can slow or stop the production of these clotting factors and cause acquired hemophilia.
