Is the carrier of color blindness colorblind?
No it is only possible.
What must be true about the father?
he is color-blind
Is color blindness a dominant or a recessive trait?
Color blindness is a recessive trait, meaning that an individual needs to inherit two copies of the gene for color blindness (one from each parent) in order to be color blind. If an individual inherits only one copy of the gene, they are considered a carrier and will not exhibit color blindness.
What was the chance that the child will be color blind?
The probability of a child being color blind depends on the parents' genetic makeup. If the mother is a carrier of the color blindness gene located on the X chromosome and the father does not carry the gene, the chances are 0% for a daughter and 50% for a son to inherit color blindness. If the father is color blind and the mother is a carrier, the chances are 50% for a daughter and 50% for a son to inherit color blindness.
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.

The family tree below shows the trait a colorblind The family tree below shows a trait a colorblindness. The only unknown is the father in the first generation what must be true about the father?
She has at least one recessive color blindness allele {apex}
Which parental pair could produce female with color blindness?
X' = color blindnessX'X'-- X --X'Yis a cross that could lead to a color blind female as the mother is homozygous recessive and the father's X chromosome is the recessive color blind trait.
What Evidence of color blindness is recessive x linked trait?
Inheritance pattern: Color blindness is caused by a recessive X-linked trait, meaning the gene responsible for color vision is located on the X chromosome. Transmission: Since males have only one X chromosome, a single copy of the recessive gene will result in color blindness. Females need to inherit two copies of the gene to be color blind. Prevalence: Color blindness occurs more frequently in males because they have a higher chance of inheriting the gene from their carrier mothers.
What are the different types of blindness?

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.
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.
