his mother because color blindness is a sex-linked trait that is found on the X chromosome, which is inherited from the mother, as opposed to the Y chromosome, which is inherited from the father. So a male can only inherit the gene for color blindness from his mom.

A male who is colorblind marries a heterozygous womanWhat percent of their total children will be color-blind?
NOW. Colourblindness we will assume, is a Sex-Linked Disorder. Hence, the sex chromosomes are involved in determinig the phenotypes of the children. XY --male XX--female XbY--colourblind male XBXb --normal female Cross: (parents) Xby * XBXb F1 progeny/offspring XBXb, XbXb, XBY, XbY 50 % of the children will be colourblind. This is a very simple question. You also need to clarify within the question if it is sex linked or autosomal.
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.
Father isn't colorblind mother is a carrier--one son is colorblind but the other is not how?
It is called x-linked alleles. It is rare for a female to have color blindness because the allele must be passed from both parents. Males only need one allele to be color blind.With the equation, color blind female and non-color blind male reproduce. Each son has a 50% chance of developing the disorder.
What would the genotypes of parents have to be for them to have a color-blind daughter?
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 a recessive allele located on the x chromosome. If a color blind man and color blind woman have one son and three daughters how many will be color blind?
Women can not be colorblind, only men. For questions like these a punnett square is useful. Men can not carry the colorblind trait, but women can. I know this is kind of confusing. When a carrier ( a woman with the color blind trait) has children with a man ( color blind or not) her kids will have 50% chance of having that trait. If its a girl, she will be the carrier. If its a boy, he will have the colorblind trait. SO TO ANSWER YOUR QUESTION: Theoreticaly, 1 of the daughters will be the carrier, and the son will have a 50% chance of being colorblind. Women can be colorblind, its just rare. About every 6400 women one is colour blind and with men, every 80 men 1 is colour blind.
Color blindness is an X-linked recessive trait A color-blind man has a daughter with normal color vision She mates with a male who has normal color vision What is the expected phenotypic ratio of t?
The phenotypic ratio will be 1:3.his son will be color blind.
Does the mother or father pass on the color blind trait?
It depends. If the child is male, the person to pass the trait on must be the mother. She may be a hybrid or color-blind herself for her to be capable of doing this. If the child is female, the father must be color-blind in addition to the mother being a carrier. Both have to donate the recessive gene to their daughter.

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.
Can parents who are not color blind have a color blind son?
It is possible. There can be traits transferred from the grand-parents or great-grandparents which come up in the childs generation.
What is the probability that a woman whose father was color blind will have a son who is color blind?
50%. 1 of the two male offspring will definately be color blind. Do a punnett square with the father having normal vision and the mother being a carrier.
Can 2 persons with normal vision produce a color blind son?
Yes.
Does the daughter and son suffer from color blindness if their mother is suffering from the color blindness disorder?
If the mother is color blind, the son will be color blind. The daughter will only be color blind if the father is also color blind. As to if they will suffer from it, that depends on their self esteem and whether or not they choose to view themselves as a victim as their mother apparently does. It should be noted that although many people have color blindness, it is rare to actually suffer from it. One possible way that one might suffer is if s/he were attempting to disarm a bomb and could not tell what color the wires were.
What is the probability that a color-blind woman will have a color- blind son?
The colorblind woman can pass the allele to all her children including sons and daughters but the daugthers will only be carriers for the trait whereas the sons will produce the trait. In order for the daughter to express the trait they would need the allele not only from the mother but from the father also. I just took an exam on this and got it right.
If your father is not colored blind but your son is where did you get the gene from that made your son color blind?
You can't tell with that amount of information. You'd need to know who in the family carried(s) the gene. Then you could see with a family tree.
