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.


Why does color blindness only occur in males?

Here is a simple explanation:Remember that all males have an XY and females have XX, colorblindness is on the X chromosome, and since it is passed on by the X chromosome, this means that females have one good X and one colorblind X . Since colorblindness is recessive, this means the good X can provide the necessary pigments and the female is not colorblind unless she receive two X's that have colorblindness (one from her mother and one from her father), highly unlikely.On the other hand, since the Y has very few genes on it, the pigment missing in the X carrying colorblindness would not be replaced and thus colorblindness would occur in males with the X colorblindness gene from the mother.More info on colorblindnessman pppl on here are smart i didn't know that!!!!! :)


What gene causes color blindness?

i don't know... is there a genetic connection??? Im wondering the same thing. Is there a genetic connection? I concluded that there is not an genetic connection, that dark hair has dark eyes for example. But i do however thing that there is a environmental connection. Both hair and eye color is effected but the environment (sunny, not sunny)


Explain why the incidence of color blindness is higher in male than females?

Overall, colorblindness is much more common in males than females due to the fact that it is a sex-linked trait. The gene for colorblindness is carried on the X chromosome. Since this is a recessive condition, males will be more likely to express it due to the fact they only have one X chromosome while the females have two.


How does the inheritance of x-linked traits differ from that of other traits?

X- linked traits can only be inherited through the x-chromosome, while other traits are inherited either by both the x and y chromosome or just the y-chromosome. Source: BSCS Biology: A Molecular Approach, Blue Version Ninth Edition

Snice the allele for colorblindness is located on the x chromosome which type of trait is colorblindness?

Sex linked


What traits like colorblindness that are carried on the x chromosome are what genes?

Traits like colorblindness, hemophilia, and Duchenne muscular dystrophy are carried on the X chromosome. These traits are caused by mutations in specific genes located on the X chromosome, such as the OPN1LW and OPN1MW genes for colorblindness and the F8 and F9 genes for hemophilia.


Colorblindness is more common in males than in females because?

it is a genetic trait carried on the X chromosome. Males have only one X chromosome, while females have two. If a male inherits the colorblindness gene on his one X chromosome, he will have the condition. However, females would need to inherit the gene on both X chromosomes to be colorblind.


What are the male genotype for colorblindness?

For example, if a mother is a carrier for colorblindness (X+Xc), and a father has normal vision X+Y, then their sons have a 50% chance of colorblindness because they inherit their X chromosome from their mother and their Y chromosome from their father.


Why can't boys be carriers of colorblindness?

With sex linked traits (the allele is found on the X chromosome) males are either affected or not (they have the defective allele or they don't). Women have two copies of the allele and can be a carrier.


Colorblindness is more common in males than in females because the allele for colorblindness is?

the allele for colorblindness is ressecive NOT dominant. more common in males because they have one x chromosome and women have two, if a deformity is found on the x chromosome in a woman, it can be masked by the other, but still have some sort of side effects, in a male, since he has one, he is effected the most. he has no other genes to mask it.


Why do color blindness occur more often in males?

It is rare in females because they have 2 X chromosomes so they have the trait that stops colorblindness, but men have an X and Y chromosome so the Y chromosome does not back up the other X chromosome and makes men have more of a chance to get colorblindness that doesn't mean girls cant get it, just means girls have a better chance to stop it.


Why are men more likely than women to be colorblind?

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.

Mother inherits color blindness what example is this?

Human being is the best example for this type of inheritance because the gene responsible for colorblindness is present on the X chromosome. Thus a heterozygous female is the carrier of colorblindness and some of the sons from this mother receiving the X chromosome with a gene for colorblindness will be colorblind because in males the other sex chromosome is Y, which remains neutral for such genes.


Is colorblindness genetic?

Yes. It is a sex-linked recessive trait found on the X chromosome.
