Colorblind male not colorblind female can there kid be color blind?

He will always be colorblind in that case because the defective gene is carried on the "X" chromosome, which males only have one of.
You see, the colorblindness gene is recessive, which means if it is paired with a regular color seeing gene it is hidden, and the person can still see the difference between red and green.
Because males have only one "X" chromosome, if they get the colorblindness gene from their mother, it will always lead to colorblindness.
Side note: Males cannot receive the colorblindness gene from their Father, as he cannot give a "X" chromosome to his son. If he did, his son would be a daughter.

If any of the parents is colourblind or has the gene, the kid may be colourblind indeed. If both parents have it, he will be colourblind.

∙ 9y agoIn this scenario the allele for colorblindness is on the X chromosome that the mother passes to her son. Because the Y chromosome passed from the father to the son is considerably smaller in size when compared to the mother's X chromosome the Y chromosome doesn't have a gene locus that corresponds to the colorblindness locus on the X chromosome. Since there is only one allele at that site this means the trait for colorblindness is always expressed based on the allele passed on the mother's X chromosome.

Witch colors are dogs colorblind from?
Dogs are not colorblind naturally, but if they have a problem and are colorblind it can be any color.
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.
What does ''Colorblind'' mean?
colorblind means that colors look like different colors to a colorblind person Colorblindness is caused by a defect in the X chromosome which is why males (XY) are more likely to be colourblind than females (XX). In a female the defect would have to be in both chromosomes, in the male the defect just has to be in one. Most commonly colorblind people cannot distinguish between red and brown or blue and green.
Is color blindness a sex linked disease?
Yes. A person is color blind if all his or her X chromosomes have the defective gene. A man have one X chromosome, and a woman has two. Thus: If only the father is color blind - The probability that the son is color blind is 0% - The probability that the daughter is color blind is 0% - The probability that the daughter is a bearer of the defective gene is 100% If the mother is a bearer of the defective gene, but is not color blind, and the father is not color blind - The probability that the son is color blind is 50% - The probability that the daughter is color blind is 0% - The probability that the daughter is a bearer of the defective gene is 50% If the mother is a bearer of the defective gene but not color blind, and the father is color blind - The probability that the son is color blind is 50% - The probability that the daughter is color blind is 50% - The probability that the daughter is a bearer of the defective gene is 100% If the mother is color blind and the father is not - The probability that the son is color blind is 100% - The probability that the daughter is color blind is 0% - The probability that the daughter is a bearer of the defective gene is 100% If both parents are color blind - The probability that the child, regardless of gender, is color blind is 100%
Can only men be colour blind?
More men are color blind than women because the recessive gene for color blindness is carried by women on one of their X chromosomes. And since they have two X chromosomes, the recessive trait is less likely to be expressed. Since men have an X and a Y chromosome, which is shorter, if a mother passes on her X chromosome with the trait of color blindness, her son will have no corresponding gene on his Y chromosome from keeping it from being expressed. So men are color blind more often than women.
If a color blind man has a color blind daughter then the mother has to be color blind as well?
The father has to be colorblind for the daughter to be colorblind because both X chromosomes must have the colorblindness gene in females because the colorblind gene is recessive. If only the mother is color deficient, then she merely passes on the gene to one of the X chromosomes in a female. If both the mother and father are both colorblind, then both X chromosomes in the female are effected and the female is colorblind. There are two scenarios in which a daughter may be born colorblind. 1. The father is colorblind and the mother is a carrier of the colorblind gene. The daughter will be either colorblind or a carrier of the colorblind gene. 2. The father and mother are both colorblind. If this is the case, then all of the children will be born colorblind.
Are goldendoodles color blind?
Every dog is colorblind
What is the probability that a colorblind female and a normal color vision male will produce an colorblind offspring?
100% of all male offspring will be colorblind. 0% of all femal offspring will be colorblind.
If a normal woman whose father is color-blind marries a colorblind man what are their chances of having a colorblind son?

Does a colorblind object reflect?
There is no such thing as a colorblind object. There are color blind people, and all object reflect they just reflect differently based on how smooth the surface is.
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 must occur for a girl to be color blind?
The girl must have a copy of the gene on each X chromosome. This means that she must have a father who is colorblind and a mother who is either a carrier or is colorblind.
If Couples that have normal vision what is the probability of them having a color blind daughter and color blind son?
It depends on a number of different factors. If colorblind is common in either family but the mother/father were lucky enough not to get it, then its a recessive gene. but if its not common in either family then its a very low chance the child will be color blind. Although, if there are numerous people on both sides of the family the probability is very high. It all depends on a lot of different factors. How dominant is the gene? How many relatives are colorblind? If there are any, and they have children, are they colorblind? The easiest way to figure out if the child will be colorblind is to have the kid and test it for colorblind-ness.
