Yep. It can only happen in girls, though - and it's very rare.

What else can I help you with?
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 if Mary and her mother are both colorblind is Mary's father colorblind too?
If Mary's mother is colorblind, and therefore carries the colorblind gene on one of her X chromosomes, then Mary would inherit that gene as well. If Mary's father is colorblind, he would have to pass on his X chromosome with the colorblind gene to Mary, making her colorblind too. If only Mary's mother is colorblind, Mary's father is likely not colorblind.
Can pink eye transfer from one eye to the other?
Yes, pink eye can transfer from one eye to the other through touching or rubbing the infected eye and then touching the other eye.
What could be the possible reasons for seeing different colors out of each eye?
Seeing different colors out of each eye could be due to a condition called anisometropia, where there is a difference in refractive error between the two eyes. This can cause one eye to perceive colors differently than the other. Other possible reasons include eye diseases or conditions affecting one eye more than the other, such as cataracts or retinal disorders. It is important to consult an eye care professional for a proper diagnosis and treatment.
Which eye is brighter than the other in the phrase "one eye is brighter than the other"?
The phrase "one eye is brighter than the other" suggests that one eye is more luminous or shining than the other.

Can someone become a police officer If they have one eye?
Yes you can, depending on the severity of your colorblindness. If you are mild red-green you should be able to tell basic colors apart. Except on the ishiAra colorblind test. There is a website that gives you the ishiAra slides and they can be memorized regardless of order that they are given. and most other colorblind tests can be memorized also unless your fully colorblind. As long as you can identify you primary colors an it doesn't affect your depth perception than it shouldn't be a problem. Good luck.

If only Mary's mother is colorblind, Mary's father is likely not colorblind.
Why are there more men that are colorblind then women?
It has to do with the slight differences in the DNA, ANSWER Colorblindness is sex linked trait. Females are XX and Males are XY. The colorblind gene is only on the X chromosome so if a male has the gene on the X chromosome then he will be colorblind. Females can have it on one X chromosome, but not the other and not be colorblind; however, they are a carrier and can pass it on. For a female to be colorblind both X chromosomes must have the gene.
A womens father is colorblind She marries a colorblind man Will there son or daughter be colorblind?
Colorblindness is an X-linked recessive disorder. This means girls (who have the sex chromosomes XX) must have a colorblind X from dad and a colorblind X from mom. Boys only need to have one colorblind X to be colorblind because they have sex chromosomes XY (and have only 1 X). If the dad has it, he has the colorblind X. If the daughter has it, she must have gotten her mom's colorblind X. If the mom is colorblind, then every child they have will be colorblind. If the mom is not colorblind, then she must be a carrier - she must have 1 normal X and 1 colorblind X. Mom is either colorblind (with 2 colorblind Xs) or she is a carrier. Dad is definitely colorblind.
Can one eye lighten before the other?
Although uncommon, it is possible for one eye to lighten. The pigment within each eys is mutually exclusive from the other. A slight difference in vein structure or blood flow could result in one eye transitioning faster than the other.
Is a carrier for colorblindness is colorblind?
Not necessarily. The allele for colorblindness is recessive. For a female, in order to be colorblind she must have to recessive alleles for colorblindness. Example: XcXc would be colorblind. XCXc would be a carrier for colorblindness, but not colorblind. For a male, because colorblindness is a sex-linked gene, he only needs one allele to be colorblind. Example: XcY is colorblind. XCY is not colorblind.
Can pink eye transfer from one eye to the other?
Yes, pink eye can transfer from one eye to the other through touching or rubbing the infected eye and then touching the other eye.

Is it possible to see slightly brighter colours in one eye than the other without any eye disease?
Yes, it is possible to perceive slightly brighter colors in one eye compared to the other even without any eye disease. This can be due to variations in the light sensitivity of each eye or differences in the cones in the retina, which detect color. It is not necessarily a cause for concern unless it is accompanied by other symptoms or changes in vision.
Which eye is brighter than the other in the phrase "one eye is brighter than the other"?
The phrase "one eye is brighter than the other" suggests that one eye is more luminous or shining than the other.
How do you have a colorblind son if neither parent is colorblind?
It is just the DNA lottery. If neither parent is colorblind that just means that one of them (or both of them) have recessive genes for colorblindness that happened to show up in this particular child.
