Human Anatomy, Physiology, and Medicine. Anything human!
Actually, it's not exactly about human beings, but my cat once gave birth to a kitten with different color eyes. They said it was sort of normal for white cats to have different eyes, such things just happen sometimes. But it was just once among all our kittens, so it's obviously not a frequent case. So it's some genetics, I guess, and something like that can easily happen to humans.
But, Uhm, In anatomy, heterochromia refers to a difference in coloration, usually of the iris but also of hair or skin. Heterochromia is a result of the relative excess or lack of melanin (a pigment). It may be inherited, or caused by genetic mosaicism, disease or injury.
Eye color, specifically the color of the irises, is determined primarily by the concentration and distribution of melanin. The affected eye may be hyperpigmented (hyperchromic) or hypopigmented (hypochromic). In humans, usually, an excess of melanin indicates hyperplasia of the iris tissues, whereas a lack of melanin indicates hypoplasia.
Heterochromia of the eye (heterochromia iridis or heterochromia iridum; the common wrong form "heterochromia iridium" is not correct Latin) is of two kinds. In complete heterochromia, one iris is a different color from the other. In partial heterochromia or sectoral heterochromia, part of one iris is a different color from its remainder.
I have Heterochomia. My eye color nor was my hair color inherited. my mom has hazel eyes and my dad has green. But I have one Yellowish Blue eye and one Reddish Green eye! (I know the red part is hard to believe but that what it looks like a lot of the time) and My mom was born with blond hair and my dad with brown... I have Red hair. I am the only one with different eyes. But im the second one in a family of 150 members to be born with red. I feel like I have a disease or something, its so weird>.<
Here's how it explains about why we have different eye colors: http://bodywonders.com/whyd-do-we-have- ... eye-colors
Multi colored eyes are called here in the US, heterochromia iridium.
my ex-father-in-law was half native-american and had one brown eye and one hazel-green eye. he also had no facial hair for a beard, lots of curly / dark hair on his head, and very little body hair.
his wife has very light blue eyes.
his sister has brown eyes, and his brother has light blue eyes.
i have blue-gray-green-teal eyes that change color. Mostly they stay green or a teal (blue-green).
my ex has amber eyes.
my father has blue eyes and my mother has blue-gray-green eyes. her family called them blue hazel.
one of my brothers has blue eyes, the other has green eyes.
my son has blue-green-gray eyes with a little tan in them. he was born with a patch of dark brown hair in a 3" circle on his head, near his forehead. the rest of his hair was blond. i imagine that when his hair turns gray, that some will be different colored where that circle was when he was so little. i was wondering while pregnant with him if he would have multicolored eyes or not. genetics is a funny thing for sure!
my father has two different coloured eyes, one blue and one brown. his eyes have been like that since the day he was born. im just wondering if this is genetic? i know his parents dont have that, my grandmother has blue and my grandfather has brown. and neither my sister or i have that, she has brown and i have blue. but im just curious if maybe it skips a generation or something like that? maybe mine or my sisters children will have two different colours? or our childrens children?
