Both my parents and all my siblings have brilliant blue eyes and dark hair. Do they just ask you what color, or do they show you the shade? Even in schools you will hear teachers talking about chappatsu brown hair , when they are referring to a students' proble … matic or delinquent behavior.

Most of us were taught in high school science class that we inherit our eye color from our parents, and that is dominant and blue is recessive so two parents with cannot have a child with brown eyes because neither parent carries the dominant form of the gene for brown eyes. Is this just a weird anomaly, or is it normal? My two brothers and I have the same green eyes with an inner ring of gold around the pupil.

YourEyeColour: Green Eye Colour: a rare human eye colour

This is actually somewhat of a myth. Human eyes don't typically change color more than once in a lifespan usually during infancy. The same goes for people with hazel eyes. One part of this pervasive belief is based on the fact that people define hazel in a number of ways. It represents a range of colors ranging from brownish to greenish and even gray sometimes. Because of this, two people who have hazel eyes can actually have very dissimilar iris colors. Another aspect of this particular eye color that probably causes confusion is the fact that eyes within the color range generally defined as hazel tend to have a higher degree of reflectivity than normal. This means that hazel-colored eyes are more likely to reflect the colors around them, such as the sky, a close surface, or what a person is wearing. Basically, it's like an optical illusion, if you'll forgive the pun. Because of the color range and propensity for hazel colored yes to reflect different colored light surfaces, people often think they're changing color entirely. This is especially true for women with hazel eyes who wear eye make-up like myself. As my eyes are where do hazel eyes come from mix of brown and green, certain eye shadows enhance one over the other. If I want to play up the green, I wear green or purple. Tans and grays play up the brown. So, if someone is unaware of this trick, my eyes may look more green one day, then more brown the other. I've read where do hazel eyes come from heard countless of times that eye color doesn't change in adulthood but mine did and in doing some research on this I've come across others who have stated the same eye color change in their adulthood. I had bright blue eyes my entire childhood, my one trait I received the most compliments on but then in my early adulthood my eyes developed an amber-gold like color near the pupil that blends into the blue making my eyes appear where do hazel eyes come from blue-ish green color. I even brought this up to my optometrist and he didn't have an answer nor did he really care. I did read somewhere that this can happen with twins. Wow, that makes so much sense and thank you. It was several years ago that I tried to find an answer to my eye color change and I didn't come across Heterochromia but instead I found many in the same boat as me who were seeking an answer to their eye color changes. Now, I just don't know what to think about my optometrist. Another Hazel dude, chipping in. I was born with blue eyes that changed to hazel during infancy. They've been a pretty dark brown with a hint of green most of my life, but in the last year or so I've noticed they've been becoming more green to the point where it's predominant now. Is this just a weird anomaly, or is it normal. Eye color is a sex-linked trait on the X chromosome, of which females have two. One chromosome in each cell is inactive, but which one is randomly determined during cell reproduction. Hence, if a female has a different eye color allele on each chromosome, her eyes can change color throughout her lifetime given random chance. This is somewhat true but not entirely. It is true that females do have two X chromosomes that can carry different alleles. However, the inactivation of one of the chromosomes occurs during early development, and is passed on to all the progeny of each individual cell, meaning that if one cell has inactivated a particular X chromosome, its daughter cells will be the same. For this reason, it is not likely that a woman would have her eye colour change later in life due to random re-activation of an allele on a inactivated X chromosome. I thought that it was entirely possible during pregnancy. We have evidence that it occurs where do hazel eyes come from I'm uncertain if anyone has studied it. It's generally believed that it may have to do with all of hormones released by the baby into the mother's blood stream. A cell dividing at the time of the babies embryogenesis may once again randomly choose an X chromosome. Again, wish I knew of a source, but the event is known to occur. As for the rest of her life, given epigenetics, what you're saying makes more sense. I wish I knew more about this though. For decades we've been saying that genetic expression is determined by the environment but until recently few people have bothered actually researching the interaction. Even if you're not studying it at the molecular level, the ultimate consequences for human behavior are remarkable. The paper Dying Young and Living Fast is eye opening I hope the site works, I'm on mobile. I the absence of severe head trauma, some sort of exceedingly rare and spontaneous glaucoma, or large doses of glaucoma medication, I can assure you that you're not witnessing an actual change in eye color. The whole mood eyes thing is just an urban myth. Changes in lighting can dramatically effect the way we perceive light and color. When someone is upset or under stress, their retinas contract. This makes the pupil smaller and exposes more surface area of the iris to direct light. If someone has particularly lighter eyes, this can often give the impression of a color change. If someone's eyes really did change color based on mood, it would be noticeable in other areas of the body that utilize melanocytes to produce pigment. I don't know if that's 100% true a close friend of mine eye color will change depending on her mood, I've known her for several years and have seen it happen personally, they change from blue, gray, dull green and bright green. Being so use to it I'm able to just look at her eyes and know if she's ok or not. I can't speak for other people, but my eyes can appear to change color based on how much light there is. That's because my eyes are actually 2 rings of color. An inner brownish-red ring, and an outer green ring. When it's bright out my pupils sp. When it's not as bright my pupils expand, hiding the brown and leaving mostly green. So, at least for my eyes, they aren't really changing colors. It's just that the more dominant color changes based on how bright it is. As a hazel eyed dude here, I strongly disagree with. My hazel eyes are almost always muddy-green. However, on some days they turn almost pure green with no brown. Even to people who have known me for decades. An interesting theory, but I wouldn't leave out a major detail like that. I would have mentioned something like my eyes seem extra green when they're bloodshot. If someone can find something better than the wikipedia. One thing I did neglect to mention was that as well as turning almost pure green they even more rarely turn gold. I think I was confusing your comment with another one which said that other people are noticing the change. Okay, I'm the opposite I guess it — people are always telling me that my eyes look different, but they always look the same to me. It's interesting to read your experiences and thanks for the correction. Light or the color of my clothes does effect how people see my eye color. I don't really notice a change between types of light ie: sun or indoor lighting. Compared to a blue-eyed or gray-eyed person, my eyes are neither blue nor gray. The yellow in the middle throws them off more towards green-kinda. If I wear a blue shirt, they look blue; ditto for gray and green and yellow. When I had my eyes dilated, there was a big circle of black ringed by dark gray--but in between was a thin ring of yellow. Your eyes aren't the colour they are because of the same reason your walls are a certain colour. Your eyes are a certain colour the same way as the reason why the sky is blue. You might notice how your eyes change depending on the light. If you're in sunlight, they may be one colour. A lightbulb may be another, and your computer screen may be another. This is because of how much of the spectrum is actually being emitted by that light source. According to wikipedia, eye colour is caused by a combination of pigment as well as scattering of light in the stroma of the iris. So would it not make sense that if the stroma of the iris slightly changes in texture for some reason if this is possible that the scattering of light would be at a slightly different wavelength, hence making the eyes appear a different colour. The same scattering effect will also depend on the light present as people have been saying. Some people, such as myself, with hazel eyes actually have two different rings of color though other colors of eyes sometimes have these too. Circumstances can cause the rings to contract or expand differentially, and clothing can emphasize one or the other color. Other people have a uniform or speckled color that just looks different depending on what colors are worn. Think of a sunset or moon rise, this color change can happen on a small scale too. My eyes are green outer and orange inner most of the time. If you want to complicate this further, try having this conversation with someone whose first language does not have separate words for blue or green. My eyes have changed dominate colors three times. The center is primarily yellow but it very commonly will go to orange to red when I am stressed. The furthest ring outside is usually a dark brown color, but lighting does make it seem blue-ish. The middle is usually green but it varies to yellow green to forest green.

Is or has anyone experienced this. Because melanocyte cells continually produce pigment, in theory eye color can be changed. My parents and 4siblings do not have green eyes, only me. Further south, going to Africa, light eyes are almost disappeared. Melanin in human irides of different color and age of donors. So, stick to saying your eyes are hazel when it comes to legal firms. Having the red hair colour is also very unique and recessive. At a very young age, they are told by people around them that they are beautiful due to the fact that hazel is a very unique eye color. Gray eyes Like blue eyes, gray eyes have a dark epithelium at the back of the iris and a relatively clear stroma at the front. My father has blue eyes, and since I must have one gene from each parent, my mother must have at least one blue-eyed gene.
