There is no chance for a colorblind daughter because the x-chromosome that comes from the male is normal and then it does not matter which x-chromosome comes from the female because colorblindness is a recessive gene, therefore there is no chance.

Recessive allele is a trait that doesn't show in one's phenotype (observable trait) if there is a dominant allelle present. Only when you inherit a recessive allele from both parents (aa for example and not Aa) does the trait show in your phenotype.
chromosome segregationIf the character is governed by a single allele and it is dominant, than its probability to be in the gamete is 75%.

Yes
Each gamete has a 50% chance of inheriting the allele for color blindness because the mother is heterozygous for the trait.
Color blindness is a sex-linked trait that is carried on the X chromosome. Since males inherit their single X chromosome from their mother, if the mother carries the allele for color blindness, her son will inherit it and be colorblind. Females need two copies of the allele to be colorblind, so they can be carriers without exhibiting the trait.
Colorblindness is an X-linked recessive disorder. This means girls (who have the sex chromosomes XX) must have a colorblind X from dad and a colorblind X from mom. Boys only need to have one colorblind X to be colorblind because they have sex chromosomes XY (and have only 1 X). If the dad has it, he has the colorblind X. If the daughter has it, she must have gotten her mom's colorblind X. If the mom is colorblind, then every child they have will be colorblind. If the mom is not colorblind, then she must be a carrier - she must have 1 normal X and 1 colorblind X. Mom is either colorblind (with 2 colorblind Xs) or she is a carrier. Dad is definitely colorblind.
Not necessarily. The allele for colorblindness is recessive. For a female, in order to be colorblind she must have to recessive alleles for colorblindness. Example: XcXc would be colorblind. XCXc would be a carrier for colorblindness, but not colorblind. For a male, because colorblindness is a sex-linked gene, he only needs one allele to be colorblind. Example: XcY is colorblind. XCY is not colorblind.

If the mother is a carrier of the colorblind gene and the father is not colorblind, there is a 50% chance that each son will inherit the colorblind gene. It is possible for one son to inherit the gene and be colorblind while the other son does not inherit the gene and is not colorblind. This is due to the random process of genetic inheritance.

She has at least one recessive color blindness allele {apex}
Colorblindness is not typically considered a disability, as it does not significantly limit a person's ability to perform daily tasks or participate in activities. However, it may pose challenges in certain situations, such as distinguishing between colors, but it does not normally impede someone from leading a full and productive life.
Color blindness is a genetic condition that can occur in both boys and girls. It is typically inherited from a person's parents, with certain genes responsible for color vision being passed down. In some cases, color blindness can also result from damage to the eye or optic nerve.
True
It is sex-linked
