If she hasn't had a son with red-green colorblindness, then a pedigree could be useful.

What is the probability of color blindness if the father is color blind and the mother carries the trait?
All daughters are normal, half the sons are color blind. The above answer is incorrect. Half of the daughters are color blind and half of the sons are color blind. Since the father always donates color blindness, it is up to the mother in each case (in the son's case, the father is irrelevant) to determine if the child is color blind or not. Since she is a carrier, the chance is 50-50.
The 10 symptoms of red-green color blindness?
can you tell me the 10 symptoms of red-green color blindness
Is color blindness a dominant or a recessive trait?
Color blindness is a recessive sex linked trait.
A pedigree chart for color blindness?
a pedigree is a chart to show how genetic disorders are passed on in a generation..color blindness is one of the genetic disorders...
Does eye color determine color blindness?
Eye color has nothing to do with whether you are color blind or not.
Is color blindness a carrier?
yes probably
Is the carrier of color blindness colorblind?
No it is only possible.
What must be true about the father?
he is color-blind
What are the possibilities of a person passing color blindness to their offspring?
Color Blindness is most commonly the result of hereditary reception of a genetically defective X chromosome. The chromosome usually comes from a carrier mother, and has a 50% chance of being passed to her son. A daughter of the same mother will have a 50% chance of also becoming a carrier, and is only likely at risk of becoming color blind if the father is color blind.
Who discover color blindness?

Do you really inherit eye color from your parents?
Through the X chromosome, usually from a mother, (whom does not show any signs of colour blindness, yet she is a CARRIER of the X chromosome) passed down to son. Males usually get this because they only posses ONE X, in their XY life.
What percentages can be expected in the offspring of cross between a female carrier for color blindness and a male with normal color vision?
50% probability that the sons produced from this union will be color blind. 50% probability that a son will not have the disease. 50% probability that a daughter will be a carrier of the allele for color blindness. 50% probability that a daughter will not be a carrier. Phenotypically this would be 1male color blind, 1 male not color blind, 1 female carrier and 1 female non-carrier. Assuming that the probability of male and female offspring is identical...this would be 25% of each genotype mentioned above. Based on phenotype, without regard to sex the percentages of normal to colorblind would be 75% to 25% with the 25% displaying the characteristic all being male.
Are all women carriers of color blindness?
Yes. See Wikipedia - Pingelap (#Color-blindness)
Why are males prone to colorblindness?
The classic red-green color blindness is carried on the X chromosome. Men get the x from their mother and the y from their father. If the x has the bad gene then they will be color blind. If a woman gets the gene from her mother she will be a carrier and able to pass it to her sons (or the carrier state to her daughters) but will be able to see because she has a good gene on the other x chromosome. There are other forms of color blindness that are inherited in other ways so women can be color blind.
Which is NOT true of color blindness?
It is not true that color blindness is most common in females. Color blindness is most common in males and approximately 8 percent of men have it.
