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.


A living thing with a dominant and recessive gene for a trait?

A living thing with a dominant and a recessive gene for a trait is heterozygous. This individual will display the dominant phenotype for that trait but may have offspring that display the recessive trait.


Is color blindness a dominant or a recessive trait?

Color blindness is a recessive trait, meaning that an individual needs to inherit two copies of the gene for color blindness (one from each parent) in order to be color blind. If an individual inherits only one copy of the gene, they are considered a carrier and will not exhibit color blindness.


Characteristic that is inherited that can be either dominant or recessive?

Eye color is an example of a characteristic that can be inherited as either dominant or recessive. Factors such as skin tone, hair color, and height can also be inherited in a similar manner.


A color-blind woman mates with a male with normal color vision Which of these results would indicate that color blindness is caused by an X-linked recessive allele?

If the couple has a color-blind son, it would indicate that color blindness is caused by an X-linked recessive allele. This is because sons inherit their single X chromosome from their mother, who carries the recessive allele for color blindness but does not express it due to her second X chromosome providing the normal color vision gene.

What is the probability that a woman who is a carrier of the colorblind gene and a color blind man will have a first son who will be color blind?

The probability is 0 (but the daughter will be a carrier of the color blind gene). This is because the gene dictating whether someone is color blind or not is linked to the X chromosome (and not the Y). The color blind gene is a recessive gene whilst the normal color vision gene is a dominant gene. Hence if a girl (XX) has one normal vision gene (from one parent) and one color blind gene (from the other parent), her normal vision gene will be dominant to the recessive color blind gene and hence she will have normal vision (but she will be a carrier of the color blind gene). If both her parents contribute the recessive color blind gene to her, then she will be color blind. For a woman (XX) to be color blind, she needs to be have both genes to be recessive (ie where there is no dominant normal color vision gene to dominate). For a man (XY), as long as the X gene contributed by his mother is a color blind gene, he will be color blind because he has no other X chromosome where a dominant normal color gene could reside. Hence, to answer the question, a man with normal color vision (XY, with a dominant normal color vision X gene since the gene can't be the recessive color blind gene otherwise he will be colorblind) and a colorblind woman (XX, both recessive color blind genes), will each contribute an X each the child. The man will contribute his only X chromosome which carries the normal color vision X gene and the woman can only contribute a recessive color blind gene. The man's normal color vision X gene will be dominant, and hence the daughter will definitely have normal vision (despite being a carrier).


What determines whether a person will have dominant or recessive hair color?

Hair color is determined by genes inherited from parents. Dominant genes for hair color will be expressed over recessive genes, resulting in the dominant color being displayed. If both parents pass on recessive genes, the recessive color will be seen.


Do you get your eye color from your parent?

Yes you get your eye color from your parent. The parent that carries one dominant gene and one recessive gene for a specific eye color and the other parent carries two recessive genes for a different eye color, you will get the eye color of the parent who carries the dominant and recessive gene. In other words, the dominant gene trumps the recessive gene. In another scenario, if both parents carry two recessive genes for a specific eye color, then you will inherit the recessive gene of that color.


Is color blind a dominant trait?

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.


Trait of an organism that can be masked by the dominant by the dominant form of a trait?

A recessive trait is a characteristic of an organism that can be masked by the dominant form of a trait. It is only expressed when an individual inherits two copies of the recessive allele. Examples include blue eye color being masked by brown eye color.


What is the color of the baby eyes if the mother have the recessive gene for blue and the father has blue eyes?

I assume you mean the mother has a dominant allele for some other color. Father is homozygous recessive for blue. Dominant allele + recessive blue X recessive blue + recessive blue The baby has a 50% chance of blue eyes and a 50% chance of getting the dominant colored eyes.
