my dad has grey-blue eyes and my mom a dark chocolate-brown color. however, my eyes are brown in the morning, hazel during the day, and green at night. they're usually a hazelly-yellow or green color... or caramel-colored. i looked up the odds of what my eye color would be if my parents had brown and blue eyes, and green and/or hazel weren't even options...
i believe eye color is polygenic, meaning it's likely it's based on the parents' genes but not definite... any more information on this? thanks a ton!
oh... and what is the name of this study? does it fit into 'biology', or am i drawing a complete and total blank? :] thanks again.

Both of my mom's parents (my mom has brown, remember) have brown eyes. Now that I think about it, my paternal (is that the word?) grandparents have blue and hazel eyes... so that may be it. Thanks again!

One more thing... thanks about 'genetics', it wasn't under the Science and Mathematics category? I was looking for it... is that a branch off of biology? I don't think so, but it's all that's there... thanks again. ;]

Haha, those squares are awesome... very helpful, I like making those, lol. ;]

If one of your parents has brown eyes, and the other blue. You have a 1 in 4 chance of being blue eyed, since brown is a dominate color. You figure it out by making a square and dividing it into 4 smaller squares. In each square put one of these combinations. Bb, BB, bb, Bb. B= Brown and b= blue. You will get a blue eyed child when two recesive (bb) genes combine.

In the simplified view, if your dad has blue eyes he must be blue-blue, if your mom has brown eyes she can either be brown-brown or brown-blue, since blue is recessive. So your parents kids have a 50-50 chance of being blue-eyed or brown-eyed. The kids will get a blue from dad no matter what, and will either get a blue or a brown from mom.
In reality, there are at least 3 genes that determine eye color, so it's even possible for a child of two blue-eyed people to have brown eyes.
Eyes that change color are rare, but I think it's possible. Lighter colored eyes, especially, look different under different lights, and with different clothes. I have light grey-blue eyes, they sometimes look blue, sometimes grey, sometimes green! My brother has light brown eyes, but I've seen them look green, too. My dad says my grandpa's blue eyes also looked green or changed to green sometimes.
All this is part of the study of genetics, which is a subset of biology.

eye color is determined by both set of parents so it is genetic. 1 thing is certain. If both parents have blue eyes all of their children will. Blue eyes are recessive and Brown eyes are dominent. Now of course there are variations of brown (ie Dark chocolate, hazel, etc) some individuals eyes do appear to change color to some extent due to lighting, etc but it will go from brown to blue. Another tidbit is most children are born with blue eyes and it takes up to six months or so to see if they keep them. That I am not sure why

As far as I know, eye color not only depends on your parents but also their parents and their parents and so on. Brown is dominant but your mom might be a carrier of a recessed gene, meaning she may be a carrier of the gene for green eyes and so might your dad. I happened to learn this in an anatomy and physiology class but I believe the study of this is genealogy.

If it somewhat is sturdy, Your father had to have brown eyes. Brown eyes are the dominate eye color and blue and eco-friendly are recessive. If 2 recessive dad and mom have a new child, the new child will maximum possibly carry the recessive gene. someplace, it somewhat is tousled. that isn't attainable, except the grand dad and mom had brown eyes. it would be like 2 white human beings having a new child and the new child is black. that isn't attainable. You father has to have brown eyes, or your mom is preserving a depressing secret

The name of the study is genetics. Your eye color is not dependant on just what your parents' eye color is but also what color their parents had. Your eye color along the every other aspect of your physical being is made up of parts of what your ancestors were like, not just your parents alone.

Even if your parents didn't have hazel eyes one of their parents may have and that keeps branching out. in the end you got that 1% probability of hazel eyes.

eyes have colors because of the melanin! melanin is in the iris of the eye, but the color is based on your genes. may be your ancestors have different eye color than your parents may coz the genes might have carried by one your parrents but it wasnt dominant and when the 2 of them combine their genes it becomes dominant then it is passed to you ^_________^

your eye color isn't just determined by your parents genes, it's also influenced by the enviroment.For example: sunlight makes your eyes appear blue (I don't know why) and darkness makes them appear black or brown.
