Man who is color blind marries a woman not colorblind and doesn't have recessive allele will their children be carriers of the color blind allele?

50%AnswerColourblindness is a sex-linked recessive mutation i.e. the mutation is carried on the X chromosome. If a colour blind man married a carrier woman they could produce a carrier daughter, a colour blind daughter, a normal son or a colour blind son. The probability of each phenotype occurring is 25%.If XC represents the normal allele for seeing colour and Xc represents the colour blind allele the genotypes of the possible offspring would be as follows:Carrier daughter = XCXcColour blind daughter = XcXcNormal son = XCYColour blind son = XcYThis information is incorrect. In fact a woman can be color blind. My mother is color blind as are my brothers. My sister and I are not though we carry the gene. I have two daughters and one is color blind and the other is not color blind.The information I gave is not incorrect - I have included the possibility of that 'mating' producing a colour blind female child.


In a survey 16 women out of 20 000 were found to be colour blind What is the expected frequency of colour blind males in this population?

Not all forms of color blindness are hereditary. There are three distinct types of hereditary color blindness, each with different frequencies in the human population, and with distinct genetic causes. Red-green color blindness is more common among males than females, but blue-yellow color blindness is not. Talking about color blindness in general, there is no reliable ratio of male-to-female prevalence.


Who carries the color blindness gene?

Color blindness is a defect in the x chromosone. Women always provide an X chromosone in their eggs. Men can either deliver an X or a Y chromosone in their sperm. Both men (XY) and women (XX) carry it. But it is more prevalent in men because they only have one X chromosone, whereas women have two X chromozones and it is very unlikely that both would be defective.


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 expected phenotypic ratio for their offspring is 1:1, with a 50% chance of being color blind (male with the X-linked recessive trait) and a 50% chance of having normal color vision. This is because the daughter is a carrier of the recessive allele, which can be passed on to her offspring regardless of the father's color vision status.


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.

Is a female colorblinded trait dominant?

It is dominant. Most likely if the female had children then all her sons would be color blind. If she herself was also color blind then all her children would be color blind too.
