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

Yes, it is called Heterochromia
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.
my stepson has a presciption of + 4.25 in one eye and + 1.50 in the other eye. what does this mean? my stepson has a presciption of + 4.25 in one eye and + 1.50 in the other eye. what does this mean?
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.
One possible cause of intermittent pressure or pulling behind 1 eye is problems with the sinuses. Allergies can also cause pressure behind the eye.
One may purchase custom eye patches at a retailer called Sweet Eye patches. Other online retailers included are Eye Patches, Eye -grafx and the Frame Huggers.
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.
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.
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.
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.

im not to sure but i have just found out that i have that problem this morning
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.
probably not i wouldn't have thought it possible with out contact lenses
If the person has a prosthetic eye AND jaundice, certainly the artificial eye will not look jaundiced.
Highly unlikely. Eye color and color blindness are not determined the same way within your DNA. -Eye color depends on what color your eyes your parents have and the dominance of specific traits and alleles. -Color blindness is linked primarily to gender. It's a sex linked mutation and occurs only on the X chromosome. Males are much more likely to be color blind than females, because it is linked only to the x chromosome. Males only have one x chromosome and females have two. For females to have the colorblind mutation, their father has to be colorblind and their mother has to be a carrier or colorblind. For a male to be colorblind their mother has to either be a carrier or color blind. It is much more likely that mother is carrier than colorblind.
Then you are an evil monstrosity from the bowels of hell or you got punched in the eye and the other other eye is red from allergies etc.
No, eye-techniques are heriditary. And passed through the clan from one generation to the other.
