The daughter's father would have to have been colour blind, and the mother would need the inheritive gene from her father (the mother doesn't nessecarily need to show it, just have a colourblind father) in order for a female to end up actually colourblind. However, it's extremely rare.
the gene for color blindness is more domiantly male
Answer
I am a woman who is red--green colorblind. The trait is carried on the X chromosome. Males receive an X chromosome from their mother and a Y from their father. If the X carries the trait of colorblindness, the male will be colorblind. Females need to receive two defective X chromosomes to be colorblind, one from their father and one from their mother. If a women has only one defective X chromosome, she will be a carrier of the trait. My father was red-green colorblind and so was my mother's father, making my mother a carrier of the trait, although she is not colorblind herself. I have two sisters who are not colorblind, as they each received a non-defective X chromosome from my mother. I knew before my son was born that he would be red-green colorblind, as the X chromosome he received from me carried the trait. My daughter is not colorblind because my husband was not, so she received only one defective X chromosome (she is a carrier of the trait).
It depends on the gender of the offspring and whether the female has the father's color-blindness.
If she has no color-blind gene, then all her children will have full color vision.
If she has the color-blind gene, then all female offspring will have full color vision. Male offspring may be color-blind, depending on which of her 'X' chromosomes is expressed in the gamete.
If the woman is pure normal vision; we can expect 2/4 chances of getting normal vision (boy or girl), 1/4 of having a girl carrying the gene, and 1/4 of having a boy being colorblind... Colorblind gene is on the X chromosome, and men only have one, so they have more chances of having that problem... So 50% normal vision, 25% carrier and 25% colorblind :D
in the punnet square it shows that a decedent like a grandparent could have a trait that a son/daughter doesn't have. for example, a grandma has blond hair, her daughter has brown hair and her son has blond hair because of his grandma.
X of the father's DNA is causing color blindness. only one of the two X from the mother's DNA is causing color blindness.
(As a fact which is related to the question but of not of a theoretical genetic nature: Colorblindness is almost only a male trait!)

Yes. Because the colorblind trait is a sexlinked trait and is found in the X chromosome that is inherited from the mother, men that only have one X chromosome will develop colorblindness if the trait is found in this gene. For a woman to get it, she would need to have the colorblind gene on both x chromosomes. Therefore the girl´s dad would have to be colorblind and the mother at least a carrier.
So, if one parent is Aa (heterozygous) and the other parent is aa (homozygous recessive) the punnett square would look like this: ___|_A__|__a_ _a_|_Aa_|_aa_ _a_|_Aa_|_aa_ The genotypes of the offspring 50% heterozygous and 50% homozygous recessive
that the parents were true-breeding for contrasting traits. NOT TRUE. If so, all the offspring would be identical genotypes. Think of a classic cross that gives you a 3:1 ratio and write it out. It would suggest that the parents were both heterozygous for a single trait.
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.
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.
The genotypes produced from a cross between Ww and Ww would be: WW Ww Ww ww -The cross between these two genotypes would produce gametes with genotypes in a 1:2:1 ratio.
The daughter's father would have to have been colour blind, and the mother would need the inheritive gene from her father (the mother doesn't nessecarily need to show it, just have a colourblind father) in order for a female to end up actually colourblind. However, it's extremely rare.
The parents genotypes will be Black and Red. BLACK being the dominant and red the recessive. The puppies genotypes would be Black and red, Black and Black, red and red.
well i only put this so i can get points but please be more specific about your question

I don't know what they are called in English, but in Hindi, your daughter in law's parents would be called "Samdhees".
Nobody really knows, people say cats are colorblind when they are not really. So I would say "No." donkeys are not colorblind
Yes. It would take too long to explain genotypes and phenotypes, just know that it is possible.
If the parents had the genotypes AO and BO, then they could have a child with Type O blood (there would be a 25% chance of this occurring).

the daughter has to be a responsible and kind person who would take care and help her parents in anything
