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.
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.
To produce female offspring with color blindness, both parents must contribute the gene for color blindness, which is typically X-linked recessive. Therefore, a mother who is either a carrier of the color blindness gene (XcX) or affected by color blindness (XcXc) and a father who is affected (XcY) can produce color-blind daughters. In this case, all daughters will inherit one X chromosome from each parent, potentially resulting in XcXc (color blind) or XcX (carrier).
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.
The probability of a colorblind child being born is 50%. This is because the male passes his Y chromosome to all his sons, and since he is colorblind, his sons will inherit the colorblind gene from him. The daughters will inherit their X chromosome from the mother and have a 50% chance of being carriers like her.
Any female born into the right family, or who marries a Duke.
When a female is heterozygous i.e. she possess one allele of disease , she is called carrier .

The preferred title is letter carrier or postal carrier.
Marriage is a wonderful event. Yes, if a female US citizen legally marries a non US citizen in the state of Michigan, they are indeed legally married.
